Problems solved by technology

For the mineral processing wastewater of polymetallic minerals, such as mineral processing enterprises with tungsten, molybdenum, bismuth, pyrite, fluorite and other valuable minerals, the mineral processing process is complicated, the flotation reagents are diverse, the discharge of mineral processing wastewater is large, and the wastewater of each process After mixing, the components are complex. During the treatment process using lime neutralization method and other technologies, there are poor flocculation and sedimentation effects and difficulties in separating mud and water. Directly affect the flotation efficiency and concentrate grade and other issues, resulting in generally low or even seldom reuse of treated wastewater

Abstract

The invention provides a polymetallic ore beneficiation wastewater recycling method. The polymetallic ore beneficiation wastewater recycling method is characterized by comprising two steps of physical treatment and biological treatment. According to the polymetallic ore beneficiation wastewater recycling method, the existing beneficiation wastewater output equipment and tailings ponds of aluminium and zinc beneficiation industries are used, wastewater treating agents such as calcium hydroxide, saponification slag and calcium carbide are added to wastewater in a mixing tank so as to ensure that suspended matters in the wastewater settle, the wastewater is purified so as to meet the technical requirements that obtained clear water is continuously used for beneficiation, the content of suspended matters in the treated water is less than 100mg / L, the pH value of the treated water is 8, and the cyclic utilization of the beneficiation wastewater is realized. The polymetallic ore beneficiation wastewater recycling method has the characteristics of low investment, low running cost, energy conservation, emission reduction and cyclic economy and is suitable for the cyclic utilization of the polymetallic ore beneficiation wastewater.

Description

technical field [0001] The invention belongs to the field of industrial wastewater treatment, and relates to a method for treating low-concentration and high-turbidity polymetallic ore dressing wastewater of heavy metals by using a suitable flocculant and a coagulant aid for two-stage flocculation precipitation, and stably discharges or reaches reuse standards after treatment. Background technique [0002] The waste water in the beneficiation process mainly comes from the three sections of ore washing, crushing and sorting. The separation process of ore mainly includes gravity separation, flotation and magnetic separation. According to statistics, it takes 4-7m2 of water to process 1 ton of ore by flotation, 20-26 m2 by gravity, 23-27 m2 by flotation and magnetic separation, and 23-27 m2 by gravity flotation. Water consumption 20-30 m2. Excluding the amount of recycled water, most of the consumed water flows out of the concentrator along with the tailings in the form of ta...
