Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where ...

Gold Ore Roasting Plant. To achieve optimum gold recovery from the certain sulfide ore body, the ore must be finely ground to achieve proper oxidation and mineral separation. The ore is separated into stockpiles after it has been mined. These stockpiles are based on gold content, sulfide content, and carbonate content.

As the load in the thickener settles to the bed, the Torque on the rake arms will be climbing. Torque is nothing more than a rotary force being applied from the rake arms to the drive shaft. It is the degree of torque that indicates to the operator the load that is in the thickener and when the rake arms have to be lifted.

The primary purpose of thickening is to increase the solids concentration of the feed stream. Gravity settling is aided by addition of chemicals called flocculants. The inlet stream going to a thickener generally is called 'feed' or 'influent'. Overflow from the unit may be called 'overflow', 'effluent', or 'supernatant'.

The pH scale is used to determine how acidic or basic the water is. Most flocculants work best at neutral conditions (pH 7) while some work independently of the pH. Flocculants are categorized as anionic, nonionic or cationic and therefore affected by pulp pH. Basic thickener operation will have you understand the simple electrics of water.
