Ministry of Land and rare earth three target rate announcement

Recently , in order to strengthen the iron, copper, lead, zinc, rare earths , potash and fluorite rational development and utilization of mineral resources, supervision and management of mining enterprises to promote conservation and comprehensive utilization of mineral resources , the Ministry announcement " of iron, copper, lead, zinc, rare earths , potash and fluorite rational development and utilization of mineral resources , such as the "three rate" minimum index requirements ( trial ) . "

Mining recovery rate , recovery rates , the comprehensive utilization rate is to evaluate the effect of conservation and comprehensive utilization of mineral resources, the main indicators .

The announcement of the Ministry of Land and mining recovery rate under the copper, lead, zinc, iron , rare earth, fluorite , potash seven different conditions minerals , mineral recovery , comprehensive utilization indicator. Where a large open-pit iron ore mining recovery rate of not less than 95 %.

Medium and small open pit mining recovery rate of not less than 90 %. Underground mining of iron ore to determine the recovery rate of 75% to 83% of the six-speed ; copper mining recovery rate , large open copper mine not less than 95% , not less than 92% of small and medium class . Underground mining based on the thickness and grade of copper ore body is different , determined the 75% to 92% of nine files ; large open lead-zinc mining recovery rate of not less than 95% , not less than 92% of SMEs , based on underground mining ore thickness, different types of lead and zinc ore grade, mining recovery rate is determined as 92% of a total of 75% to 27 stalls indicator; rare earth is divided into two types of rock and ionic , using heap leach mining recovery rate of ionic rare earth mining process is not less than 87% ( leaching phase ) , 70% ( all phases ) , ionic situ leach mining of rare earth mining recovery rate of not less than 84% ( leaching phase ) , 67% ( all phases ) ; solid rock salt , potassium mining recovery rate of not less than 61% , chloride -based salt lake brine potash salt mining recovery factor of not less than 70% recovery rate ; fluorite surface mining recovery rate of not less than 90 % of underground mining recovery rate is determined not to less than 80% , not less than 73% two steps .

The announcement also for copper, lead, zinc, iron , rare earth, fluorite , potash seven minerals beneficiation recovery , comprehensive utilization indicators required to make detailed regulations.
