Choice of mining and processing methods the simple aim in selecting and implementing a particular mine plan is always to mine a mineral deposit so that profit is maximized given the unique characteristics of the deposit and its location, current market prices for the mined mineral, and the limits imposed by safety, economy, environment.
The chinese began to engage in the practice of tin mining around 700 b.Today, tin can be found in china, thailand and indonesia, and it is also mined in brazil, peru and bolivia.Tin is obtained by carbothermic reduction of the oxide ore, which is produced by heating the ore in a furnace.Other key tin facts tin is the 49th most abundant.
International mining im is a global publication covering mining and minerals processing technology, methods, equipment and services.Read principally by the mining industry itself, it helps extractive operations, both surface and underground, keep abreast of the latest innovations and solutions to help them lower costs, increase performance and availability, enhance safety and of course.
Processing methods.Although there are a number of different diamond recovery technologies being utilized worldwide, the two principal types are rotary pan plants and dense media separation dms.Both methods are in actual fact used for bulk material reduction and require a further process for the final diamond recovery.
Vein and disseminated tin deposits are less common, and mined by similar hard rock mining methods used for other non-ferrous ores such as zinc.The ore is broken by drilling and blasting, transported to a processing plant where it is crushed and ground and then concentrated using gravity methods.
The renison mine produces a tin concentrate of grade varying between 50- 60 sn with internal process designed to reduce penalty metals such as iron, sulphur, tungsten and copper.The metallurgical process is complex and applies several stages of gravity-type concentration as well as sulphide and oxide flotation, regrinding and acid leach methods.
