Copper Lead Zinc rare earth "three rate" indicator ban companies announced the development of non-compliance

In order to strengthen the mining recovery rate under seven minerals iron , copper and other different conditions , recovery rates , the indicator comprehensive utilization of mineral resources to promote the rational exploitation of these supervision and management of mining enterprises to promote conservation and comprehensive utilization of mineral resources . MLR January 6 issued a " iron, copper, lead, zinc, rare earths , potash and fluorite rational development and utilization of mineral resources ," three rate " minimum index requirements ( Trial)" ( hereinafter referred to as " requirements" ) .

Ministry of Mineral Resources and Reserves Division of Homeland official also highlighted that the time to carry out spot checks and inspections , regularly publish a list of compliant and non- compliance with the requirements of this indicator mining enterprises , the implementation of social supervision , dynamic management . For indexes reach the requirements will not be through the development and utilization of mineral annual inspection .

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% , 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.

The concern of rare earth resources are divided into two types of rock and ionic , using heap leaching mining ionic rare earth mining recovery rate of not less than 87% ( leaching phase ) , 70% ( all phases ) , in situ dip ionic rare earth mining mining recovery rate of not less than 84% ( leaching phase ) , 67% ( all phases ) .

Hebei Province Bureau of Geology and a professional told the " Daily Economic News" reporter , mining recovery rate is the percentage of the mining process mined ores or the amount of metal ore mining area owned or metal reserves. Mining recovery rate is higher , indicating mined ore , the more little lost in a mine ore , resource use efficiency , the better development of the mine .

He explained that in the actual mining process, miners may consider such factors as the cost of mining easy choice , taste high priority to start, and for mining rights have been obtained but not easily abandoned mined ore mining, which will cause a great waste .

The "request" a highlight that defines the scope and responsibilities of supervision and management of land and resources department standards , emphasizing the provincial land and resources department is responsible for the implementation of the indicator area of ​​mining enterprises to conduct supervision and management, from time to time carry out spot checks and inspections , regularly publish a list of compliant and non- compliance with the requirements of this indicator mining enterprises , the implementation of social supervision , dynamic management .

Above the Department of Homeland responsible person, reach for the indicator will not be through the development and utilization of mineral annual inspection . For special cases, the provisions of the mining enterprise shall submit an explanation and demonstration report , submitted to the original mining rights registration and management authorities.

It is understood that the requirements for this indicator is lower than the actual resource conditions are better indicators of the provinces , the provisions of " provincial land and resources department in accordance with the characteristics of the administrative area of mineral resources , the development of this standard is not less than the indicator ."

The official said that the timely establishment of a sound "three rate " standard, designate the source of ecological civilization "red line" , is to implement the spirit of the Third Plenary Session , the transformation of government functions and strengthen standards established to protect the environment from the source important measures. Another background strict regime of mineral resources is to reduce dependence on foreign exports . ,

Hebei Bureau of Geology and analysis to reporters , said the release of " three rate" standard seven minerals , compared to five last year in the industrial production of mineral resources and accounting applications should be much larger , it is more conducive to resource utilization efficiency and environmental protection.
