ABSTRACTOne of the principal problems in flotation of copper complex ores is the presence of pyrite and copperactivated 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 ...

At Newcrest's Telfer gold mine, a strategy of regrinding pyrite rougher flotation concentrates has been proposed to increase gold recovery and reduce cyanide consumption in the CIL circuit. The regrinding will be followed by an additional copper/gold flotation stage, where copper minerals need to be separated from pyrite.
Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.
For more than a century now, flotation has been at the heart of the mineral processing industry. In this month's SPOTLIGHT FEATURE ARTICLE, direct from the November issue of INTERNATIONAL MINING magazine, John Chadwick examines new technologies and applications from some of the key players in mineral flotation, a technique that is so important to the global industry.
flotation tailings stockpile and insitu ore reserves. Runofmine ore was proposed to be milled and floated in a twostage flotation circuit to produce lead and zinc concentrates, followed by flotation of the remaining sulphides in the zinc tailings to produce a goldcontaining arsenopyrite/ pyrite concentrate.

Removing pyrite from coal and p yrrhotite from pentlandite play a critical role in coal and nickel production, respectively, to meet the stringent restriction on SO 2 emission. The present project investigates first the mechanism of xanthate adsorption on gold using Atomic Force Microscope (AFM), then the depression of pyrite and pyrrhotite ...

MILLING. The current Kumtor plant flowsheet reflects the finegrained nature of the gold and its intimate association with pyrite and consists of crushing, grinding, pyrite flotation and double regrinding of the flotation concentrate.
Flotation circuits are often operated at a pH range of to The exact range at any given plant is optimized for the ore at that site. Lime is often used to raise the pH of the pulp and also reduce the flotation of iron pyrite. Particle Size. The particle size to which the ore is .
The reconfiguration of the Chelopech mill during 2013 will bring annual production capacity of pyrite concentrate to 400,000 tonnes. The Agreement provides for the purchase by XGC of up to 200,000 tonnes per year of pyrite concentrate from Chelopech Mining EAD, a whollyowned subsidiary of DPM and owner of the Chelopech mine, from 2014 to 2016.
Fine disseminated ore extent of growing with the continuous mining. Fine grained minerals have become an important part of the mineral separation and it gets a lot of people's attention. This paper expounds the status of fine particle flotation process and fine particle separation facility.
