PDF Technical Document: Acid Mine Drainage Prediction

Extraction and beneficiation operations associated with mining activity increase the rate of these same chemical reactions by exposing large volumes of sulfide rock material with increased surface area to air and water. The oxidation of sulfide minerals consists of several reactions. Each sulfide mineral has a different oxidation rate.

Material and Energy Requirement for Rare Earth Production

Aug 21, 2013 · At Bayan Obo, the mineral ore contains 4.1% of REO and the average recovery rate is 50%; consequently, the extraction of 1 tonne of REM requires mining almost 50 tonnes of mineral ore and 6 GJ of energy input. Monazite and xenotime have hardness values of about 5 Mohs, both of which are similar to that of apatite.

Beneficiation of Iron Ores – IspatGuru

Apr 03, 2014 · Iron ore is a mineral which is used after extraction and processing for the production of iron and steel. The main ores of iron usually contain Fe2O3 (70 % iron, hematite) or Fe3O4 (72 % iron. magnetite). Ores are normally associated with unwanted gangue material. Grade of iron ore is usually determined by the total Fe content in the ore.

The process mineralogy of gold: The classification of ore

The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold (<10 µm) locked
