Electrochemical Evaluation of Pyrite Films Prepared by Plasma Spraying [PDF]

, 2009
Thermally activated batteries use electrodes that are typically fabricated by cold pressing of powder. In the LiSi/FeS2 system, natural (mineral) pyrite is used for the cathode.

Flotation separation of pyrite and carbonate minerals from a carlin-type gold deposit in Guizhou by a new combined collector and its adsorption mechanism

Scientific Reports
Flotation is the most common method for effective separation of pyrite and carbonate minerals from Carlin-type gold deposits. The effect of conventional xanthate collector on flotation of a Carlin-type gold mine in Guizhou province is poor, and it can ...

The Pyrite and Marcasite Electrodes [PDF]

, 1965
Pyrite and marcasite may be used as the indicating electrode in neutralization reactions. In acid solution the pyrite and marcasite electrodes behave almost identically with the platinum electrode with differences arising (1) in the presence of strong ...

Mineralization and trace element distribution in pyrite using EMPA in exploration drill holes from Cheshmeh Zard gold district, Khorasan Razavi Province, Iran

Journal of Economic Geology, 2015
Introduction Pyrite is the most abundant sulfide mineral in low sulfidation ore deposits. Experimental studies have shown that low-temperature ( 200°C) from hydrothermal or metamorphic fluids (Butler and Rickard, 2000).
