copper mining and processing from mine to copper plate

The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached. First the copper ore from a open pit mine is blasted, loaded and transported to the primary crushers. Then the ore is crushed and screened, with the fine sulfide ore (~0.5 mm) going to froth flotation cells for recovery of copper.

MATLAB174; tool for determining first order flotation kinetic

Flotation is a physicochemical separation process that utilises the difference in surface properties of the valuable minerals and the unwanted gangue minerals. The theory of froth flotation is complex, involving three phases (solids, water, and froth) with many subprocesses and interactions, and is not completely understood. (Wills, 2005)

US Patent for Froth flotation method for stibnite Patent

Disclosed is a process for concentrating stibnite (antimony sulfide) and separating it from iron sulfide minerals such as pyrite by froth flotation using untreated recirculated water or mine water which is acidic and may be heavily loaded with metal salts. The process features the use of a watersoluble zinccyanide complex salt to depress iron sulfide minerals.

For floatable particles, the principal mechanism is true flotation (i.e. bubble attachment and

Mineral Attachment and Bubble Bursting in Flotation Froths

Mineral separation is therefore a function of the amount of valuable material loaded on the bubble shells, as well as the amount of gangue material entrained in the liquid channels separating the bubbles (Plateau borders). As a result, the separation performance of the process is affected by mineral attachment and drainage or bursting in the froth.

An Overview of Optimizing Strategies for Flotation Banks

A flotation bank is a serial arrangement of cells. How to optimally operate a bank remains a challenge. This article reviews three reported strategies air profiling, masspull (froth velocity) profiling and Peak Air Recovery (PAR) profiling. These are all ways of manipulating the recovery profile down a bank, which may be the property being exploited. Mathematical analysis has shown that a
