Small Scale Gold Mining and Mini Crusher in Congo
XSM is one of China's largest crusher and milling machine manufacturers, has the most advanced crushing and milling machine manufacturing technology. People around the world to provide the best crusher has been xuanshi long goal.
High gold prices,persistent poverty and a shortage of employment opportunities in Congo have all contributed to an increase in artisanal and small-scale gold mining activity in recent years.The expansion of the sector has brought new political and analytical attention to a phenomenon which has been largely overlooked in the past.Notable among some of these recent analyses of artisanal and small-scale mining is a tendency to view such operations as homogeneous.
process of gold mining
The initial process of gold mining starts with prospecting.In prospecting, the ore quality,鈥渧ein鈥 geologic formation and ore assaying are examined. An area with a good ore quality is prepared for tunneling. in tunneling, holing and drilling are done using pick and shovel. Others who can afford it use electric hammer jacks. These initial stages of prospecting and tunneling are the expertise of the abanteros, whose knowledge of gold mining has been shaped by years of experience.Some migrant miners from the lowlands have also learned the skill. in South cotabato,the abanteros came from diwalwal, monkayo, compostela Valley.
gold crushing processing plant
Crushing was undertaken using jaw and gyratory crushers,followed by grinding in a rod mill and then gravity circuit.Because of the small-scale design of this circuit, it could easily be used in ‘batch mode’ to allow bulk sampling of certain development rounds (25 t to 50 t) or parcels of stope ore.This capability was extremely important during the evaluation of mining blocks.
