How a Thickener Works. Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle ...
The greatest uncertainty in predicting the performance of a full scale CIP or CIL plant from results that are generated in small scale batch tests (typically 1–10 L of pulp), is the impact of scale up on mixing efficiency and hence the rate of gold cyanide adsorption on carbon. In our experience, mass transfer rates in small scale bottle roll ...
A commerative gold ingot from the first gold pour using our cyanide-free recovery method.
