Shibang Copper ore mining process

In Lifestyle 20 views

Copper ore crusher is mined either at via open pit mines or underground mines. The beginning for all copper is to mine sulfide and oxide ores through digging or blasting and then crushing. In the crushing process, the copper ore is broken into small grain sizes of less than 25 centimeters in diameter by primary crusher, then crushing it to walnut-sized pieces by secondary crusher or fineness crusher.

The use of copper

Most copper is used for electrical equipment (60%); construction, such as roofing and plumbing (20%); industrial machineri, such as heat exchangers (15%) and alloys (5%). The main long established copper alloys are bronze, brass (a copper-zinc alloy), copper-tin-zinc, which was strong enough to make guns and cannons, and was known as gun metal, copper and nichel, known as cupronickel, which was the preferred metal for low-denomination coins. Copper is ideal for electrical wiring because it is easily worked, can be drawn into fine wire and has a high electrical conductivity.

Copper mining process

There are two distinct types of copper ore crusher, the sulfide ore and the oxide ore. The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached. First the copper ore from a open pit mine is blasted, loaded and transported to the primary crushers. Then the ore is crushed and screened, with the fine sulfide ore (~-0.5 mm) going to froth flotation cells for recovery of copper. The coarser ore goes to the heap leach, where the copper is subjected to a dilute sulfuric acid solution to dissolve the copper. Then the leach solution containing the dissolved copper is subjected to a process called solvent extraction (SX. vibrating screen ). The SX process concentrates and purifies the copper leach solution so the copper can be recovered at a high electrical current efficiency by the electrowinning cells. It does this by adding a chemical reagent to the SX tanks which selectively binds with and extracts the copper, is easily separated from the copper (stripped), recovering as much of the reagent as possible for re-use. The concentrated copper solution is dissolved in sulfuric acid and sent to the electrolytic cells for recovery as copper plates (cathodes). From the copper cathodes, it is manufactured into wire, appliances, etc. that are used in everyday life. Below are some photos of the process equipment at an Arizona Copper Mine.

SBM is a professional copper ore crusher benefication equipment manufacturer and supplier, our copper ore crushing fleet contains: PE jaw crusher (primary crusher), JC jaw crusher (Secondary crusher), PF impact crusher, PFW impact crusher (secondary crusher), cone crusher (fineness crusher),VSI crusher (fineness crusher). We also can supply portable crusher and mobile crusher to the clients according to the demands. After the crushing process, the crushed copper ore will be taken to the concentrator for grinding into fine powder.
