INTRODUCTION TO MINING 11 MINING’S CONTRIBUTION TO CIVILIZATION Mining may well have been the second of humankind’s earliest endeavors— granted that agriculture was the ﬁrst The two industries ranked together as the primary or basic industries of early civilization Little has changed in the
Solution mining provides an opportunity to mine soft rock at depths in which conventional mining would not be feasible Due to the decreased requirement for labour in solution mining, lower operating costs are obtained The operational cost of potash solution mining in Canada is compared to conventional mining methods in Table 2:
It is used most frequently when the percentage of the desired metal in a rock is small, or to extract remaining metals from waste rock after conventional mining In Chile, which currently produces one-third of the world’s copper, many of the most copper-rich ores have already been mined

A schematic diagram of the conventional process for the production of copper and the SX/EW process can be seen here Conventional Copper Extraction Conventionally, copper is recovered by a pyrometallurgical process known as smelting In this process copper ore is mined, crushed, ground, concentrated, smelted and refined Get price
Conventional copper production The smelting furnace(s) continually produce(s) molten matte (50 – 75% Cu); cranes are used to carry ladles of matte into converters, which function in parallel to produce batches of blister copper (998% Cu) Fig 3 Pyrometallurgical operations that are common to conventional and unconvensional copper smelters

The Malundwe and Chimiwungo deposits are mined sequentially by open-pit methods Apart from copper, Lumwana Mining also produces cobalt, gold, and uranium Lumwana ore, which is predominantly sulfide, is treated through a conventional sulfide flotation plant, producing copper concentrate for smelting
The flow chart in Figure 21017 shows a process for recovering precious metals such as Au, Ag, and PGMs from scraps using a conventional copper smelter In Japan, this process is primarily used to recover Au The process applies the chemical affinity of precious metals for Cu and its sulfide
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the .
Prior to the development of the Isa Process technology, the standard approach was to use a starter sheet of high-purity copper as the initial cathode These starter sheets are produced in special electrolytic cells by electrodeposition of copper for 24 hours onto a plate made of copper coated with oil (or treated with other similar face-separation materials) or of titanium
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore) Having a quick look now at how porphyry ores are treated and the metals extracted
