Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use. The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and …
For the purpose of implementing security and detection of hazards inside a coal mine, an IOT based coal mine safety monitoring and alerting system project is proposed.
This chapter discusses robotics and automation for mining and process control in mineral processing. Teleoperation of mining equipment and control strategies for grinding and flotation serve as examples of current development in the field.
Automation is often more basic in mining than in other industries and is frequently limited to simple control of motors, equipment or certain parts of processes.
Robotic process automation or RPA handles repetitive business processes using software robots to perform tasks, parse, and trigger error-free responses 24/7.
In addition, you will be introduced to library-compatible function und function block programming. You will get to know the Function Block Diagram (FBD) programming language and use it to program a function block (FB1) and an organization block (OB1).
The latest article in our series reviewing the fundamentals of mining looks at the method of block caving. Block caving is a gravity-based underground mining method that involves breaking up the rock mass located at depth into pieces. This method is particularly suitable for low-grade minerals or with disseminated mineralization.
A Functional Block Diagram (abbreviated as FBD) is a graphical representation of a functional process via blocks and diagrams that is easier for a reader to understand and interpret. An FBD helps us determine the function between output variables and input variables via a set of rudimentary blocks and diagrams that are connected with arrows ...
What is Functional Block Diagram (FBD)? The primary concept behind an FBD is data flow. A Functional block diagram describes a function between input and output through a functional block. A FBD program is built using function blocks connected together to define the data exchange. The connecting lines will have a compatible …
The purification uses an electrolyte of copper (II) sulfate solution, impure copper anodes, and strips of high purity copper for the cathodes. The diagram shows a very simplified view of a cell.
The continuous mining system for block caving mines was modeled under laboratory-scaled conditions. Indeed, there is a good agreement between the El Salvador mine test results and the scaled values in terms of productivity, where copper ore fragments, gravel, and brick were used.
In this Article, We Will explore various block diagram reduction rules, discuss the advantages and disadvantages of this technique, and examine its applications. Additionally, a solved example will be presented to illustrate the practical application of block diagram reduction rules in simplifying complex systems.

Although ladder logic is still by far the preferred programming language in our industry, there are other languages that you may find appealing. Structured text, instruction lists, sequential function charts and function block diagrams are all options that are available.
A block flow diagram (BFD) is a drawing of a chemical processes used to simplify and understand the basic structure of a system. A BFD is the simplest form of the flow diagrams used in industry. Blocks in a BFD can represent anything from a single piece of equipment to an entire plant. For a complex process, block flow diagrams can be …
For almost a decade, IMA Engineering company has been developing sensor applications to better separate ore from the waste from early exploration to modern bulk ore sorting (or particle sorting). To move from theoretical studies to practical evaluation several new concepts have been successfully tested with sensor solutions.
How digital innovation can improve mining productivity | McKinsey. Article (PDF-2 ) The global mining industry is under pressure. In the short term, falling commodity prices are squeezing cash flow. Looking ahead, many existing mines are maturing, resulting in the extraction of lower ore grades and longer haul distances from …
ABB will upgrade the mine hoist at KGHM's "Lubin" copper mine in southwest Poland, which is in one of the oldest mines in the Polish Copper Zone.

Beginners guide to thickeners. Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). The driving force for the separation is gravitational, where the differences in phase densities drive the ...
