Abstract

Abstract:

Abstract: According to the existing issues includes part of the old process equipment，high energy consumption of the equipment as well as processing ability that is difficult to match the mining capacity，thus the work about capacity expansion and remolding is carried out.Concretely，for flotation process，a coarse，two fine，three sweep are changed to two series of work，and the process consists of a coarse，two fine，two sweep，and the overflow type ball mill （MQY3660） as a new grinding equipment.In addition，Using hydrocyclone FX500 replaces the original screw pole machine，and new pressurization filter XMZGFS200/1250-U is applied so as to satisfy the requirement of gold concentrate filter，and part of the slurry pump，plunger pump and other auxiliary equipment need to be updated.The results present that handling capacity is up to 1 500 t/d after remolding of dressing plant，the capacity in a year is more than 160 thousand tons，and annual output of gold metal is around 330 kg，which leads to extra profit about 10 million RMB.

Key words: gold mine, ore dressing, capacity expansion, equipment remolding, technological flowsheet remolding, improve benefit
