The processing of the ore is done in a dressing plant.Generally including the following three basic process.
1. Preparation before separation
Raw ore (raw coal) crushing, screening, grinding, grading and other processes.The purpose of this process is to separate the useful minerals from gangue mineral monomers and to dissociate all kinds of useful minerals from each other.Some dressing plant, according to the nature of the ore and the needs of separation, set up before the separation of ore washing and pre-selected throwing waste rock operations.
2. Separation
By means of gravity separation, magnetic separation, electric separation, flotation and other mineral processing methods, the useful minerals are separated from gangue and the useful minerals are separated from each other to obtain the final mineral processing products (concentrates, tailings and sometimes middle ores).
3. Treatment after separation
It includes dehydration of all kinds of concentrate and tailings products.Fine material precipitation concentration, filtration, drying and washing water clarification cycle reuse, etc.
