Mobile crusher and grinding mill used for copper ore processing in Sweden
Mobile crusher and grinding mill used for copper ore processing in Sweden, Sweden Aitik copper mine is one of four mines owned by Boliden. Located near Gallivare, northern Sweden, the low-grade Aitik copper deposit was discovered in the early 1930s. Bulk-mining technology made exploitation feasible in the 1960s and mining at Europe’s first large, low-grade open pit copper mine started in 1968 at a production rate of 2t a year of ore. Since then, a series of pushbacks have increased output to approximately 19t a year. The concentrator, which expanded in parallel, ships over 200,000t a year to the Ronnskar smelter.
Copper Ore processing plant
Copper ore processing plant Flotation cell/flotation separator applicable for separating non-ferrous metal, black metal, noble metal, non-metal mineral, raw body and materials of chemical industry, which are subject to coarse separation, swept separation, fine separation and floatation, so the useful ore are reclaimed.
Autogenous and ball mill grinding is followed by conventional flotation, the system design being typically ‘Boliden’. The new ultrafine mills supplied by Liming Heavy Industry(shanghai) are the largest in the world, each with a grinding capacity of 2,200t per hour. They are fed with run of mill sized minus 400mm that are delivered from a stockpile with a capacity to store 200,000t. The ore is transported via a 7km-long conveyor system.
About 3.5km of the conveyor runs underground from the old in-pit crusher and a new semi-mobile in-pit crusher installed at a depth of 285m within the mine. Another semi-mobile in-pit crusher was installed on the surface between the Aitik pit and the Salmijärvi satellite pit where waste stripping is processed.
How copper is mined and copper ore mining crushing plant:
First the copper ore 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.
In the primary crusher, the ore is broken into smaller pieces of less than 25 centimetres in diameter. Crushed ore is then loaded on to a conveyor belt which takes it to the storage bin. In the storage bin, ball mills and other grinding machine grind the ore until it is a fine powder.
During the crushing process, Liming Heavy Industry(shanghai) has improved the capacity and end crushing products with our secondary crusher and tertiary crusher. The total energy consumption is reduced considerably.
Comparing the operation efficiency of CS cone crusher and hydraulic cone crusher, we find CS cone crusher achieved better results in tertiary crushing. And if installing the same number of secondary and tertiary crushers, a part of operation is transmitted from tertiary to secondary crushers where the liner wear is three times less, which significantly influences on the cost reduction in the crushing process.
Mobile crusher as copper ore crushing processing equipment
Mobile Crusher as a copper ore mining equipment is fully adaptable to all mobile crushing needs, it set up a new range of business opportunities for contractors, quarry operators, recycling and mining applications.
