The Copper Mountain SAG mill is 10363 mm 34 feet in diameter and 6096 mm 20 feet long. It is a grate discharge mill with an inside diameter of 10363 mm 34 feet and a grinding length of 5334 mm 17.5 feet. The mill is driven by two 8,500 horsepower ABB motors. Figure 2 - The 34 x 20 SAG mill
The effects of grinding on the floatabilities of copper-nickel sulfides from Duluth gabbro were investigated. At the same mesh-of-grind copper, nickel, and cobalt recoveries were higher and residual sulfur in the tailings was lower with autogeneously ground pulps. With ball-mill ground pulps the residual sulfur could not be lowered even at ...

Stage 3 Roasting At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite CuFeS 2.From the formula, it is clear that iron and sulfur have to be removed in order to produce copper.

Sep 26, 2019 The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.
Beginning in the mid 1980s a new technology, commonly known as the leach-solvent extraction-electrowinning process or, SXEW Process, was widely adopted. This new copper technology utilizes smelter acid to produce copper from oxidized ores and mine wastes. Today, worldwide, approximately 20 of all copper produced is produced by this is process.

As an important indicator of flotation performance, froth texture is believed to be related to operational condition in sulphur flotation process. A novel fault detection method based on froth texture unit distribution TUD is proposed to recognize the fault condition of sulphur flotation in real time. The froth texture unit number is calculated based on texture spectrum, and the probability ...
The invention discloses a method for comprehensively utilizing copper-bearing pyrite resources, which comprises the steps copper-bearing medium- and low-grade pyrite ore which is difficult in flotation separation of copper and sulfur is levigated, and copper-bearing high-grade sulfur concentrated ore can be obtained after copper and sulfur bulk flotation and a plurality of times of refinement ...
