Mar 11, 2021· Why process control? In a real situation there are a lot of disturbances in the process. In the thickener, there can be many disturbances, like feed disturbances: volumetric flow, changing ore types, particle size changes and Rheology conditions. That is why it is important to have good control over the process.

Precious Metals - Gold and Silver. For over a hundred years, miners have used dilute alkaline cyanide solutions (e.g., sodium cyanide [NaCN] around pH 10-11) to leach (dissolve) gold and other precious metals, from their ores. The gold is usually in the form of small flakes mixed with other minerals.
