As the main source of industrial ore of lithium group, spodumene is also widely used in metallurgy, chemical industry, power generation, medicine and so on. The spodumene beneficiation methods mainly include manual sorting, heavy-medium method, magnetic separation, flotation and combined beneficiation method.
Quartz sand has been widely used in glass, metallurgy, aviation, electronics, machinery, refractory materials and other industries.Too many impurities will affect the value of quartz sand. Among many impurities, iron is the most harmful impurity.The common methods of iron removal from quartz sand include mechanical scrubbing, flotation, magnetic separation and acid leaching.
When siderite contains less impurities, it can be used for Refined iron.The beneficiation processes of siderite include gravity separation, magnetic separation, flotation, and magnetization roasting-weak magnetic separation.
Nickel ore is mainly divided into copper-nickel sulfide ore and nickel oxide ore. The main beneficiation process of copper-nickel sulfide ore is flotation.the beneficiation methods of nickel oxide are mainly two kinds of pyrometallurgy and hydrometallurgy.
The beneficiation methods of gold mines include gravity separation, flotation and cyanide extraction. Gold mineral processing equipment includes flotation cell,desorption electrolysis equipment and jig etc.
Heap leaching is also a common gold extraction process and is considered to be the most economical gold extraction process at present. Gold ore heap leaching process mainly includes six stages: ore preparation, leaching pad construction, heap building, leaching solution preparation, liquid distribution & collection, and pregnant solution processing.
Because of its unique physical and chemical properties, quartz sand plays an important role in aviation, aerospace, machinery, electronics and IT industries.Quartz sand purification processes include scrubbing & desilting, magnetic separation, flotation, acid leaching, and microbial leaching.
The placer gold mining process mainly includes is mainly divided into two stages, namely preparation operation and ore beneficiation operation.Commonly used equipment are jig, shaking table spiral chute, etc.
Pyrite is also called pyrite and pyrrhotite. More than 85% of pyrite ore is used to produce sulfuric acid. There are three main beneficiation processes for pyrite, single gravity separation process, single flotation process and gravity separation-flotation combined process.
Flotation is a very common process in gold beneficiation, and is suitable for the treatment of sulfide gold ore and polymetallic gold sulfide ore with fine gold particles and high floatability. Gold ore flotation technology has been researched earlier, widely used, and mature in technology, and is suitable for most gold-bearing ores.
