A "unit operation" is one step in a process to convert a raw material into some useful chemical product. It's one of the blackboxes which appeared in process and performs some physical (as opposed to chemical) change. In this course, we will learn staged separation techniques and how to design equipment for distillation (usually tray towers), liquid-liquid extraction and leaching. You will ...

leaching behaviour of Au-bearing ores, several methods have been proposed. Yet, bench-scale bottle roll testing has become a well-established procedure to gain preliminary insight about the leachability of a particular Au-bearing ore. The procedure seems straightforward, relatively easy to apply and is percepted to provide reliable and fast data that would form the basis for further assessment ...

Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns. It is then extracted from the pregnant leach solution by adsorption on carbon or resins. This ...

Equipment for extraction and leaching must be capable of providing intimate contact between two phases so as to effect transfer of solute between them and also of ultimately effecting a complete separation of the phases. For so general an operation, naturally a substantial variety of equipment has been devised. A very general classification of equipment, their main characteristics and ...

There are many different types of equipment used for leaching. Most of these pieces of equipment fall into one of two categories: Percolation ("Liquid added to solids") - The solvent is contacted with the solid in a continuous or batch method. This method is popular for in-place ore leaching or large scale "heap" leaching. Popular for extreme amounts of solids.
