There are significant tin reserves in the dumps and tailings from Llallagua. Currently, this waste is being processed using gravity concentration or a combination of with final stage froth flotation. A process mineralogy study their products after processing Llallagua was carried out to determine failings system order contribute designing an improved new scheme. The feed tailings, concentrate, ...

For various sorts of hard coal, enrichment by flotation is used for feed consisting grains smaller than 0.5 mm. Regarding process automation, coal a multidimensional, dynamic nonlinear object control, which the main control signal flow rate agent. Typically, in Polish coal-processing facilities monitoring and systems can only measure parameter waste quality (content ash tailings). This naturall...

Polymeric aluminum ferric sulphate(PAFS) was prepared from high-sulfur bauxite flotation tailings and red mud by roasting, acid leaching polymerization. The effects of temperature, time, liquid-solid ratio on the rate Al3+ Fe3+were investigated. optimal conditions are as follows: temperature 100℃, time 90 min, sulfuric concentration 4.5mol/L 5 mg/L. Infrared spectroscopy X-ray diffraction analy...

The objective of this work was to study the effect muscovite and biotite on flotation chalcopyrite molybdenite in seawater, use sodium hexametaphosphate silicate improve copper molybdenum recoveries. impact inorganic dispersants settling properties resulting tailings also studied. It found that depress with depressing being stronger at pH 11 than 9. Sodium increased recoveries seawater. These r...

Cement paste is an already well-known material used in ore mining. It mainly to fill excavation areas and the tailings from surface return underground mines. In this way, amount of deposited degradation terrain are reduced. The itself can be as artificial barrier between mining works watercourses. Significant economic environmental benefits expected using cement paste, which would contribute su...

Flotation wastes are becoming a valuable secondary raw material and source of many metals semimetals worldwide with the possibilities industrial recycling. The flotation tailings contain oxide sulfide minerals that have not been sufficiently stabilized form acidic mine waters, which in turn contaminate groundwater, rivers, reservoi6sediments. An effective way to recycle these is recover through...
