Comminution circuits are used to optimize the liberation of valuable mineral particles from waste rock for downstream separation processes. When the target grind is not achieved (under-grinding), it results in a higher number of unliberated gold particles. This in turn causes a loss in gold recovery and therefore revenue.

Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.

Calculate Economic Metal Recovery The control of a milling operation is a problem in imponderables: from the moment that the ore drops into the mill scoop the process becomes continuous, and continuity ceases only when the products finally come to rest at the concentrate bins and on the tailing dams.
Every process step for mineral recovery can be replicated and tested for viability and efficiency by Gekko's world-class metallurgical laboratory service. The metallurgical laboratory has state-of-the-art equipment for sample preparation, grinding, flotation, gravity separation, gold leaching, as well as a leach pilot plant to test protocols ...
INERAL grinding is the most energy consuming and most costly procedure in mineral-processing processes. It is a key to deliver desirable mineral concentrate grade, metal recovery rate, and operation efficiency by regulating opera-tional indices, namely, grinding product particle size (GPPS) and circulating load (CL), which is known as ...

The standard cyanide leach process consists of grinding the ore to about. 80% – 200 mesh, mixing the ore/water grinding slurry with about 2 pounds. per ton of sodium cyanide and enough quick lime to keep the pH of the solution. at about 11.0. At a slurry concentration of 50% solids, the slurry passes.
A Mineral Jigs installed in the grinding circuit in cyanide mills have proved very successful in increasing recovery. It is always advisable to recover your mineral values as soon and as coarse as possible. Net return of an operation may be increased by production of bullion at the mine instead of shipping ore, or by the treatment of concentrates.

The unique grinding technology, which Swiss Tower Mills Minerals AG offers for the mineral processing industries, has been well proven over more than 40 years in the industrial mineral segment: over 200 fine and ultra-fine grinding mills are in operation, with a total installed power of over 300 MW.
Mineralogy is related to the identification and occurrence of economical minerals to be recovered by concentration and leaching processes. The practice of gold minerals beneficiation is optimized by using the information obtained from applied mineralogy.
Grinding size. Determining an optimal grinding size can maximize the recovery of target minerals in the subsequent flotation process. The grinding size is too large, and some ore particles and non-ore particles cannot be separated, thus preventing their flotation.
