Ore mined is processed at the Kalgold plant where the crushing circuit consists of a primary jaw
crusher, a screen and a secondary cone crusher. The primary crusher is located adjacent to the
pit and is in open circuit, with the crusher product being conveyed to the plant. In the plant this
material is fed into the cone crusher, which is in closed circuit with a screen which takes the
product from this crusher. The product from this circuit is the feed to the mill circuit:
The total solid feed to the primary crusher is 1200 t/hr. In analysing the performance of this
circuit, consider two size fractions, namely the particles larger than 1cm and those passing 1cm.
In the feed to the primary crusher only 15% of the material is already finer than 1cm. Assume
that the jaw crusher will break 30% of the material coarser than 1cm to finer than this size, while
the cone crusher will break 50% of the material above 1cm to finer than this size. Assume that
the screen’s performance is such that the partition number for the coarser particles is 0.8, while
it is 0.3 for the finer particles.
Carry out a mass balance over the circuit calculating the mass flowrates of each of the
components in each of the streams. What is the percentage passing 1cm in the crusher circuit
product/mill circuit feed?
We need to calculate the mass flowrates of each of the components in each of the streams and the percentage passing 1 cm in the crusher circuit product/mill circuit feed.
To calculate the mass flowrate of each component in each of the streams: F = C + T (1)
Where,
F = Feed flowrate (t/hr)
C = Circuit product flowrate (t/hr)
T = Tail flowrate (t/hr)
Circuit Flowrate:CF = QF × CF(2)
Where,
CF = Circuit flowrate (t/hr)
QF = Fractional volumetric flowrate of the stream
CF = VCF × γF (3)
Where,
VC = Volumetric flowrate of the stream (m3/hr)
γ = Density of the stream (t/m3)
Stream 1 - Feed to Primary Crusher: The total solid flowrate to the primary crusher is 1200 t/hr.
Let the fractional flow of particles larger than 1cm be F1 and that passing 1cm be F2.
F1 = 1 - 0.15 = 0.85
F2 = 0.15C1 = 0.3 × 0.85 × 1200 = 306 T/hr (material broken by jaw crusher larger than 1cm)
C2 = 0.5 × 0.15 × 1200 = 90 T/hr (material broken by cone crusher larger than 1cm)
T1 = (1 - 0.3) × 0.85 × 1200 = 714 T/hr
T2 = (1 - 0.5) × 0.15 × 1200 = 60 T/hr
Stream 2 - Product from Primary Crusher: The product from the primary crusher is the feed to the secondary cone crusher.
F1 = 0.7
F2 = 0.3
C1 = 0.8 × 0.7 × 306 = 171.36 T/hr (material not broken by secondary cone crusher and coming back to primary crusher)
C2 = 0.5 × 0.7 × 306 + 0.3 × 90 = 143.1 T/hr (material broken by secondary cone crusher larger than 1cm)
T1 = (1 - 0.8) × 0.7 × 306 = 48.96 T/hrT2 = (1 - 0.5) × 0.7 × 306 = 107.1 T/hr
Stream 3 - Product from Secondary Cone Crusher: The product from the secondary cone crusher is fed to the mill circuit.
F1 = 0.7,
F2 = 0.3
C1 = 0.8 × 0.3 × 143.1 + 0.7 × 171.36 = 235.32 T/hr
C2 = 0.5 × 0.3 × 143.1 = 21.47 T/hr
T1 = (1 - 0.8) × 0.3 × 143.1 = 28.62 T/hrT2 = (1 - 0.5) × 0.3 × 143.1 = 35.84 T/hr
Stream 4 - Mill Circuit Feed: The product from the secondary cone crusher is fed to the mill circuit.
F1 = 0.7,
F2 = 0.3.C1 = 235.32 T/hr
C2 = 21.47 T/hrT1 = 48.96 T/hr
T2 = 107.1 T/hr
Percentage passing 1 cm in the crusher circuit product/mill circuit feed:
Percentage passing 1 cm in the crusher circuit product = 100 × (T2 of Stream 2)/(C1 of Stream 2) = 100 × 107.1/235.32 = 45.51%
Percentage passing 1 cm in the mill circuit feed = 100 × (T2 of Stream 4)/(C1 of Stream 4) = 100 × 107.1/235.32 = 45.51%
Hence, the percentage passing 1cm in the crusher circuit product/mill circuit feed is 45.51%.

Passwords shall not be transmitted in the clear outside the secure domain
True
False
True. Passwords should never be transmitted in the clear outside the secure domain. The transmission of passwords in clear text is a major security risk and can lead to unauthorized access and compromise of sensitive information.
When a password is transmitted in clear text, it means that it is not encrypted or protected in any way during the transmission process. This allows anyone who intercepts the communication to easily read and capture the password, exposing it to potential misuse.
To ensure the security of passwords during transmission, it is essential to use secure protocols such as HTTPS or other encrypted communication channels. These protocols employ encryption techniques to protect the sensitive information, including passwords, from unauthorized access.
Additionally, it is crucial to follow best practices such as password hashing and salting on the server-side to store and handle passwords securely. Hashing transforms the password into an irreversible string of characters, making it extremely difficult for attackers to retrieve the original password even if they gain access to the stored data.
By adhering to these security measures, organizations can protect the confidentiality and integrity of user passwords, reducing the risk of unauthorized access and potential security breaches.

a program written in ____ is the most basic circuitry-level language.
The most basic circuitry-level language is machine language. A program written in machine language is considered the most basic circuitry-level language. Machine language is also called the first generation language (1GL).
Machine language is the basic circuitry-level language, and it is also known as the first-generation language (1GL). It is the lowest level of programming languages, and it is also referred to as assembly language. It is a low-level programming language that is written in binary code, consisting of 1s and 0s, which the computer processor can understand and execute.
Machine language programs are, however, difficult to write, understand, and debug. The languages require a programmer to know the hardware architecture of the computer, including the instruction set, data format, memory addressing, and other basic features. Assembly language is a low-level language, but it uses a symbolic representation of the machine language, which makes it simpler to read, write, and debug.Most programmers use high-level languages to create computer programs, such as Python, C++, Java, and others.Know more about the Machine language

______ is the process of initiating contact between two bluetooth devices.
The process of initiating contact between two Bluetooth devices is called "pairing."When you want to connect two devices using Bluetooth, you must first pair them. This process establishes a link between the two devices so that they can communicate with one another.
Pairing is essentially just a one-time setup process that needs to be done when you're setting up a new device for the first time. After the devices are paired, they should be able to connect to one another automatically whenever they're in range and their Bluetooth is turned on.Pairing can be done in a variety of ways, depending on the specific devices you're working with. Some devices may require a PIN or passcode to be entered during the pairing process to ensure that only authorized devices can connect to them. Other devices may use more advanced security features to prevent unauthorized access.

what is a collection of computers that are all peers
A collection of computers that are all peers is known as a peer-to-peer network. In a peer-to-peer (P2P) network, each device or node in the network is treated as equal and can act as both a client and server in sharing files and resources among other devices on the network.
A peer-to-peer network is usually used in smaller networks, such as a small office or a group of computers in a home network. The biggest advantage of P2P networks is that they are easy to set up and do not require a dedicated server. These networks do not have a centralized server to manage the communication between nodes. Instead, each node in the network communicates with other nodes directly and in real-time.
Each node on the network can share resources, such as files, printers, and storage devices, with other nodes on the network. This makes it a cost-effective solution for small organizations or groups that need to share resources without investing in expensive network infrastructure.On the other hand, a disadvantage of P2P networks is that they can be less secure than client-server networks, as each node is connected directly to other nodes on the network. This makes it easier for malware and viruses to spread between devices on the network.
Additionally, without a centralized server to manage network traffic, P2P networks can become slow and congested as more nodes join the network.

what are the three separate capacities in the information processing model?
The information processing model consists of three separate capacities: sensory memory, short-term memory, and long-term memory.
1. Sensory memory is the initial stage of processing where sensory information from the environment is briefly held. It has a large capacity but a short duration, lasting only a few seconds. For example, when you see a word on a screen, it is briefly stored in sensory memory before moving on to the next stage.
2. Short-term memory, also known as working memory, is the second stage of processing. It has a limited capacity of about seven items and a duration of around 20 seconds. It is responsible for actively processing and manipulating information, like when you mentally rehearse a phone number before dialing it.
3. Long-term memory is the final stage of processing, where information is stored for longer periods. It has an unlimited capacity and can last a lifetime. Long-term memory is further divided into explicit (conscious) and implicit (unconscious) memories. For example, remembering a historical event is an explicit memory, while riding a bike is an implicit memory.
In summary, the information processing model consists of sensory memory, short-term memory, and long-term memory, each with different capacities and durations.
