Converting Tailings Dumps into Mineral

A number of developments in mineral processing technology have combined to make the retreatment of numerous tailings dumps a profitable proposition. This is particularly the case for tailings dumps created from the processing of platinum group elements (PGEs) from the UG2 reef in the Bushveld Complex (BC) of South Africa, which are now being retreated to recover chrome.

What is a theoretical grade-recovery curve? An

The theoretical grade-recovery curve for an ore is a definition of the maximum expected recovery by flotation of a mineral or element at a given grade. This is defined by the surface area liberation of the value minerals and is consequently directly related to the grind size utilised in the process. The theoretical grade-recovery can be readily used to quickly identify potential recovery
