Stone crushing plant in Peru - SBM stone crushing machine

SBM has exported many stone crushers, grinding mills and complete stone crushing plant to Peru for Peru mineral industry development, especially in gold mining, copper mining and zinc mining industry.

Peru's gold production increased by 9% in 2003 to reach 171,551 kg. Exports were valued at US$2.05 billion an increase of 38% from 2002. Gold represented 47% of the value of all mining exports in 2003 and 23% ogf Peru's total exports. Minera Yanacocha and Minera Barrick Misquichilca contributed 68% of the total output, informal gold miners contributed 17% and Cia Minera Ares and Cia de Minas Buenaventura each contributed 3%. SBM stone crushing plant is the necessary equipment in gold mining process. Gold in the rock ore were very low, in order to extract gold, the ore must be processed by gold mine processing plant. In this process, many gold mining types of equipment are used, such as gold refining and purifying equipment, but the ore firstly must be crushed and grinded, thus the gold is separated from the ore. General, using jaw crusher to crush ore first, then using cone crusher to crush ore secondly. Grinding mill machine grind the crushed ore to powder. The final step is to separate glod from the ore.

Stone crushing machine in Peru

Peru is the world's number 3 producer of lead and zinc and one of the leading producers of silver. In 2003 Peru produced 307,705 t of lead and 1,368,606 t of zinc and 2,775t of silver. Exports were worth US$201,3 million for lead and US$528,7 million for zinc. Volcan Cia Minera is the country's largest lead producer with output of 54,254 t in 2003. The company also produced 224,382 t of zinc and 296t of silver. Antamina became Peru's largest zinc and silver producer in 2003 with outputs of 400,703 t and 316,8 t respectively.

SBM stone crushers are necessary equipment in zinc mining. During the exploration of zinc ore, some crushing and screening equipment will be needed, including various crushers, vibrating screen, and sand making machine, etc. In the extraction of lead and zinc, raw materials are first sent into primary crushing plant through the hopper. It can make more effective crushing by adopting proper crushing methods in compliance with the mechanical strength characteristics of lead and zinc ores. In the primary crushing plant, lead and zinc crusher is usually jaw crusher or gyratory crusher with high capacity and big feed size. After achieving the required particle size, they are sent into the grinding mill by belt conveyor for further pulverization.
