Flotation Cell For Pyrite And Copper Pyrite

ABSTRACTOne of the principal problems in flotation of copper complex ores is the presence of pyrite and copper-activated pyrite in moderately alkaline pHs. Misreported pyrite into copper concentrates dramatically declines copper grade and its recovery. In this study, the effect of sodium sulfide, sodium metabisulfite (SMBS), and their dosages (100, 200, 300, and 400 g/t) were investigated on ...

Influence Of Pyrite Content On The Flotation Of ...

Influence Of Pyrite Content On The Flotation Of ...

In the flotation of copper ores several processing plants report that copper recovery is affected by the proportion and type of pyrite in the ore, with the effect becoming more intense when the feed ore particles are fine, i.e. in fine regrinding. In this work, a model mix mineral system consisting of chalcopyrite and pyrite with varying pyrite content (in the range 20-80 wt. %) was used to ...

An Alternative Circuit For Chalcopyrite

An Alternative Circuit For Chalcopyrite

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

Arsenopyrite is separated from a mixture with pyrite by contacting the mixture with a sulfitic agent providing HSO 3 - ions at elevated temperature and pH below about 8 for a period sufficient to impart a selective depression property to the arsenopyrite. On addition of a collector the pyrite is rendered floatable, enabling froth flotation to achieve a concentrate rich in pyrite and tailings ...

Ph/Orp Measurement Copper Flotation Process

Ph/Orp Measurement Copper Flotation Process

A high pH is important in copper ore processing to maximize this mineral’s flotation properties. Most copper ore slurries tend to be acidic. Plants typically add lime to the slurry in the mill or floatation circuit, increasing its alkalinity. A typical copper operation contains many flotation cells, often with a pH sensor in each cell.
