(PDF) GRAVITY CONCENTRATION OF GOLD FROM …

Minimizing the Size of the Gravity Concentration Circuit Many process engineers view enhanced gravity concentration in gold grinding circuits as a nuisance and a security risk. In part, this is probably due to the chequered history of enhanced gravity concentration, and the inability to predict the impact a gravity circuit will have on overall performance of a given plant.

Grinding Circuit

Circulation of material occurs in several parts of a mineral processing flowsheet, in grinding and flotation circuits, for example, as well as the crushing stage. In the present context, the circulating load (C) is the mass of coarse material returned from the screen to the crusher relative to the circuit final product (or fresh feed to the circuit), often quoted as a percentage.

Grinding is a powdering or pulverizing process using the rock mechanical forces of impaction and attrition. The two main objectives for a grinding process are: To liberate individual minerals trapped in rock crystals (ores) and thereby open up for a subsequent enrichment in the form of separation.

Grinding Circuit

Grinding circuits are fed at a controlled rate from the stockpile or bins holding the crusher plant product. There may be a number of grinding circuits in parallel, each circuit taking a definite fraction of the feed. An example is the Highland Valley Cu/Mo plant with five parallel grinding lines (Chapter 12).
