Introduction to Mineral Processing Chevron Phillips Chemical

The response of many minerals to the flotation process is often dramatically affected by pH. Flotation circuits are often operated at a pH range of 7.5 to 11.5. The exact range at any given plant is optimized for the ore at that site.

Copper extraction

Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copperinconcentrate (usually 2729% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena. Chalcocite concentrates typically

Recovery of metal values from copper slags by flotation

The second route was flotation of the slags, roasting of the flotation tailings with pyrite and leaching. The second route was found to be suitable for the treatment of the copper slag studied. In the flotation step, a copper concentrate containing approximately 11% Cu was produced with a 77% recovery while 93% of the cobalt stayed in the tailings.

Depressants for Pyrite / Flotation depressants

PIONERA BioPolymers can offer a significant economic advantage in flotation of iron/sulfur bearing minerals in reducing smelter penalties, increasing grade and recovery of metallic concentrates. Flotation results indicate that PIONERA BioPolymers, at each dosage, significantly reduce pyrite than conventional pyrite depressants.

The polymetallic separation flowsheet of copper/lead bulk flotation copper/lead separation priority to floating zinc and pyrite (recovering of gold and silver) from the bulk flotation tailings was used based on the ore characteristics.

Developing a Bulk Circuit Suitable for Chalcopyrite Pyrite

A simpler flotation circuit with lower operating and capital costs for treatment of such coppergoldpyrite ores with an elevated pyrite head assay was sought in this work. After characterizing the ore, the objective was to apply bulk rougher flotation of both the copper minerals and pyrite for the coppergoldpyrite ore at natural pH.

The depression of pyrite in selective flotation by

Pyrite, a gangue mineral, is commonly associated with valuable base metal sulfide minerals and the separation of pyrite from these valuable sulfide minerals by flotation is difficult. In this study, a type of biopolymers, modified from lignosulfonates, was used to reject pyrite in chalcopyrite flotation based on the previous investigations.

The separation of chalcopyrite and chalcocite from pyrite

There is a general industrial observation that chalcocitedominant copper ores are more difficult to treat in particular in cleaner flotation after regrinding (Wightman et al., 2011). The oxidation of copper minerals plays a critical role in copper flotation and also the separation from pyrite.

Froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
