A waste-free processing method for lead-zinc ore mining

Abstract

A waste-free processing method for lead-zinc ore mining. A stone material plant is set up in an adjacent ore dressing plant, and a sedimentation tank is set up and built in the adjacent ore dressing plant and stone plant; The ore slurry and tailings slurry are transported to the sedimentation tank for sedimentation treatment; the stone plant processes the waste rock extracted from the mine along with the ore, and outputs stone, machine-made sand, and slurry; stone and machine-made sand are used as building materials for paving, bridging and construction Or the materials for mine filling engineering are sold externally; the slurry is transported to the sedimentation tank or concentrator for further processing; the tailings sand after sedimentation in the sedimentation tank is transported to the mixing station, mixed with cement and machine-made sand to form a cementitious material for mine filling engineering Use; the waste-free processing method for lead-zinc mine mining of the present invention not only completely solves the problem of potential safety hazards caused by the open-pit storage of existing mine waste rock and tailings, but also improves the economic benefits of mining enterprises, so it has extremely high promotion value .

Description

technical field [0001] The invention relates to the technical field of lead-zinc ore mining and beneficiation treatment, in particular to a waste-free processing method for lead-zinc ore mining. Background technique [0002] With the development of society and the continuous acceleration of the urbanization process, the domestic demand for mineral products is increasing. However, in the process of mining resources, a large amount of waste rock and tailings are generated and require a lot of land resources. More importantly, Waste rock slopes and tailings dams themselves have major safety hazards. Professional personnel are required to regularly monitor and maintain waste rock stacking and tailings dams. It not only causes waste of land resources, but also causes pollution of surface soil environment; in addition, in the process of mining, it is necessary to carry out filling works, which requires a large amount of river sand, and river sand is collected in large quantities a...

Problems solved by technology

[0003] In order to overcome the deficiencies in the background technology, the present invention discloses a non-waste processing method for lead-zinc ore mining: a stone plant is set up in the adjacent existing dressing plant, a sedimentation tank is set up in the adjacent dressing plant and the stone plant, and the dressing plant 1. The stone plant is connected to the sedimentation tank through the tailings slurry pipeline and the water pipeline, and the stone plant is connected to the mineral processing plant through the stone slurry pipeline; the mineral processing plant processes the ore mined from the mine, outputs the concentrate and tailings slurry, and transports the concentrate to the smelting plant The factory does further smelting and processing, and the tailings slurry is transported to the sedimentation tank through the tailings slurry pipeline for sedimentation treatment; the stone factory processes waste rocks mined together with the ore from the mine, and outputs stone materials, machine-made sand, and stone pulp; stone materials and machine-made sand are used as road paving The sales of building materials for construction, bridging, and construction have increased the economic income of mining enterprises, and at the same time solved the landslide problem of existing waste rock piles; the slurry is transported to the sedimentation tank or the slurry pipeline to the concentrator through the tailings slurry pipeline for further processing Treatment; the water after the tailings slurry is settled in the sedimentation tank is transported back to the concentrator and stone plant for reuse through the water pipeline; the tailings sand after the sedimentation in the sedimentation tank is transported to the mixing station, mixed with cement and machine-made sand to form a cementing material for supply The use of mine filling projects solves the problem of high cost of using river sand and greatly reduces the cost of cementing materials for mine filling projects
