01/08/2020· Ore with a grade higher than 0.25% Cu is fed to milling-flotation plant to produce copper concentrates, while the ore with grade lower than 0.25% Cu is sent to HBL-SX-EW to produce copper cathode via SX-EW. Because the copper resource consists mainly of secondary copper sulfides with high pyrite, and the mine is located in a region of high rainfall, a large volume of acid mine drainage is

Copper Lead Zinc Ore Flotation Plant Pineer Mining

Its natural floatability is good, so flotation is the main method of extracting the copper ore. According to the processing order of the useful mineral, the copper ore processing/mining can be divided into precedence flotation, equivalent flotation, mixed flotation and partial flotation. The process choice of copper ore flotation is determined by the raw ore properties.

In this case study, an oxidized low-grade porphyry copper ore, milled to 70 % passing 150 µm, was used as a proxy for a typical porphyry-type copper sulfide tailings. The ore had a sulfur and copper grade of 3.84 % and 0.16 %, respectively. Pyrite (7.03 %) and chalcopyrite (0.12 %) were the major sulfide minerals. Flotation was carried out in stages (maximum 4), using methyl isobutyl carbinol

In the following smelting process, copper is transformed into a “matte” containing 50 70 percent copper. The matte is either flash converted or processed in a converter resulting in blister copper of 98.5 99.5 percent copper content. In the

Environmental Impact of Flotation Processing

Environmental Impact of Flotation Processing . Valuable minerals in an ore can be separated from each other, and from worthless minerals, by the froth flotation process. The need for a process to extract ore arose from major sulfide mineralization after the oxide ores had been depleted. The technology involves first crushing the ore, typically to a particle size of about 5 to 50 micrometers

Flotation testing indicated that an increase in copper recovery of approximately 1% could be achieved, or that a grind size increase of approximately 30 μm may potentially yield equivalent copper recovery due to the microwave-enhanced liberation observed. However, statistical analyses demonstrated that it is difficult to attain confidence in recovery increases of approximately 1% even when
