flotation of gold and goldbearing ores sciencedirectapplication of flotation on a reasonable scale within the goldmining industry commenced in the early 1930s following the introduction of watersoluble flotation collectors (specifically xanthates and dithiophosphate collectors) that allowed differential flotation of sulfide minerals, followed by the installation of pyrite flotation plants on numerous gold mines in south africa.

electrochemical properties of pyrite, pyrrhotite, and flotation circuits, and the application of this information in the field of electrochemistry15. one of the most important separation stages in flotation circuits is the separation of pyrite and pyrrhotite from other sulphide minerals. understanding of activation and depression of sulphide minerals, such as pyrite

recovery of pyrite from copper tailings by flotation the objective of this study was to design a flotation circuit to produce pyrite concentrate of commercial interest from fresh tailings generated in a concentrator plant from the atacama region, chile. to achieve the objective (1) the effect of ph, collector and frother dosage, and conditioning time on the recovery in the rougher flotation

Advantages of pyrite flotation design

flotation of pyrite metallurgist amp; mineral processing sodium silicate was somewhat effective in causing a differential or selective flotation of copper, as chalcopyrite from pyrite by keeping pyrite from floating. sodium hydroxide and sodium sulfide gave, in most cases, a distinct separation of sphalerite from chalcopyrite; i.e., a high copper and low zinc by suppressing the flotation of sphalerite.

the adsorption of cu species onto pyrite surface and its the adsorption of cu species onto pyrite surface and its effect on flotation were investigated by using microflotation tests, firstprinciple calculations, and xps surface analysis. the results indicated that the flotation of pyrite appears to be activated with cuso 4 only at alkaline ph, while being depressed at acidic and neutral ph.

fundamental surface chemistry and froth (specifically two types of quebracho tupasol ato and tupafin ato) in the froth flotation process as a depressant for gangue minerals. two ore types, copper and fluorite, were researched. the primary gangue mineral of interest was calcite for the fluorite ore, while it was pyrite for the copper ore.

synthesis of 4a zeolite from kaolinitetype pyrite resource use of the tailings is essential. kaolinitetype pyrite tailings include kaolinitetype pyrite gravity separation tailings and kaolinitetype pyrite flotation tailings (kpft). kpft are a type of lowquality kaolin with impurities such as iron and titanium. therefore, synthesizing 4a zeolite using kpft as the raw material is possible.

pyrite tailings recovery by flotationpyrite has long been used as a source of sulphur, and its recovery as a byproduct from the flotation of certain base metal ores is a well established practice. large tonnages of mill tailings which have accumulated as a result of various milling operations frequently contain significant amounts of pyrite. in many instances these tailings can be treated to yield pyrite concentrates that are a
