Tailings Process Must Protect The Environment

Mineral processing equipment plant in China during the beneficiation of ore

, usually comes with the many tailings, seriously endangering the health of the environment, so that the concentrator to be good to imagine the treatment of tailings, tailings disposal equipment (e.g., tailings recycling machines) is necessary, the operator also traced to understand the formation of tailings, professional processing equipment manufacturers Henan hongxing to help you out:

The tailings contain a large number of useful components (gold, silver, copper, iron), its concept is relative; some ore into the concentrator crushing, grinding, and choose other jobs in the current technology level, ore useful minerals sub-elected one or more of the concentrate product; tailings discharged while the slurry state; the tailings large number of yield is generally 80-90%; fine mineral ratio is smaller, non-ferrous mineral processing equipment plant fine rate of only 10% -20% of the mineral; rare metals cannot be recycled, but with the science and technology to progress, the tailings to a useful component can re-development and utilization; This will undoubtedly improve mining machinery plant to economic benefits to a large extent.

Tailings disposal is not only related to environmental protection, rational use of resources to the problem, but also with the legal aspects of land issues; the higher the ore grade, the greater the rate of fine mineral tailings production is the less; large number of tailings if not properly handle harm will be great; mineral processing equipment plants discharge to tailings water often contains large quantities of pharmaceutical and hazardous substances; the source of the beneficiation process to flotation Pharmacy and ore to metal elements, common to cyanide, xanthate, black drugs, pine oil, copper ion, lead ion, zinc ion and in some cases there will be arsenic, phenol mercury; tailings water of these hazardous substances not meet emission standards, are harmful to humans, livestock, fish and farm; mineral processing equipment plant tailings cannot be any emissions, otherwise it will cause the river systems near the soil or groundwater resources to pollution, and serious harm to corporate development;

In recent years, with the technical development of mineral processing equipment, in 1985 the mine field weakening - strong magnetic separation technology re-election to the tailings recovery of tens of thousands of tons a year from the tailings, tens of thousands of dollars worth of subway concentrate is being further regrinding the tailings re-election, so that the tailings of gold, silver, copper, iron and other useful minerals are fully recycled; Therefore, the tailings of the concentrator to properly handle has a very important to meaning.
