Abstract

The invention discloses a process for treating a tailings pond and comprehensively recovering heavy metal. The process comprises the following steps that (1), magnetic separation is carried out on raw ore; (2), part of a mixture A after magnetic separation is iron ore concentrate, and part of a mixture B is subjected to flotation; (3), part of a mixture D is reselected after flotation; and (4), part of a reselected mixture F serves as tailings. Heavy metal such as copper, lead, zinc, sulfur, iron and mercury in the tailings pond are effectively recovered; and the tailings reach the national discharge standard, and the problems of surface soil and underground water pollution, safety, environmental protection, environmental management and the like are effectively solved.

Description

technical field [0001] The invention relates to the field of recovery of heavy metals in tailings, in particular to a process for comprehensively recovering heavy metals in tailings reservoir treatment. Background technique [0002] my country is a kingdom of non-ferrous metals, rich in mineral resources, but because the early mineral processing technology is not very mature, a large amount of heavy metals are discharged into the tailings pond along with the tailings during the mineral processing process. Heavy metals in surface soil and groundwater have seriously exceeded the standard. With the needs of the society and the continuous expansion of production capacity, a large number of dressing plant tailings have been produced all over the country, which has caused great difficulties in the treatment of dressing plant tailings pools. The technology of recovering heavy metals from dressing plant tailings is widely used in my country. It has been in a state of research, so th...
