Description
Technical field：
The present invention relates to a kind of weight, magnetic, floating beneficiation combined method to produce useless water purification method, belongs to underground mining technical field.
Background technology：
The world today is faced with population, resource and environment three major issues; the problems such as worldwide environmental crisis just makes the mankind be faced with unprecedented stern challenge, and environmental pollution, depletion of the ozone layer, acid rain harm, global warming, living species diversity fall sharply serious threat development, human health and the social stability of World Economics.Water resource is a kind of valuable source irreplaceable in various resources, water resources and environment is closely related, also it is closely related with human development, due to the fast development of modern industry, industrial water pollution has become the major reason of environmental degradation, therefore water resources problems has become one of major issue that the world attractes attention.
Beneficiation wastewater processing is the important embodiment of built environment friendly enterprise, Green Mine, the especially mine close to urban fringe, the important indicator for being treated as building city mine of beneficiation wastewater.Caused waste water is referred to as beneficiation wastewater in ore dressing plant magnetic separation, gravity treatment, floatation process.The processing mode of beneficiation wastewater is unanimously handled using the measure of Tailings Dam natural packing, solar radiation, natural supernatant for many years, backwater part returns to production procedure application, because it is handled, ore properties are different, and outer displacement mass does not reach national environmental protection monitoring standard always in part ore dressing plant.
Metal mine can produce substantial amounts of beneficiation wastewater in process of production, these waste water qualities are complicated, composition is various, containing various heavy, beneficiation reagent and other pollutants, if carrying out outer row without processing, serious harm will be produced to surrounding ecological environment, if recycled in Returning process, harmful substance in waste water will constantly accumulate, and can have a negative impact to production technology and equipment, it is therefore desirable to select suitable processing method to handle beneficiation wastewater.Currently used processing method has chemical precipitation method, absorption method, microbial method, artificial swamp method etc., although these processing methods each have the advantages of certain, generally by mining production condition, the limitation of the factor such as environmental condition and processing requirement.It is relatively preferable for example with chemical precipitation method heavy metal treatment effect, but organic matter poor processing effect.Absorption method can effectively handle heavy metal wastewater thereby, but during adsorbent reactivation, pollutant can regenerate again.Wetland method area occupied is big, long processing period, it is also difficult to meets processing requirement, therefore how to select a kind of beneficiation wastewater treatment method rationally, effectively, practical, is the problem that current metal mine enterprise generally faces.
