Introduction to Mineral Processing or Beneficiation

The most common and notable example of this are precious metal values (gold, silver etc.) where the beneficiation process is applied directly on run-of-mine ores followed by the extraction of gold and in some cases silver as a relatively pure metal within the mineral processing circuit.

How Does A CIP Gold Processing Plant Work?

The main process of the CIP gold processing plant to extract gold from ore and convert it into pure metal can be divided into 6 steps: crushing, screening, grinding, classification, carbon slurry gold extraction and tailings treatment.
