Embodiment Construction

[0010] The present invention can add a mercury circulation cooling device and a recovery device on the basis of ore antimony processing equipment, add a cooling device composed of multiple rows of twisted steel pipes on the original antimony processing sewage pipe and put it into a cooling device filled with water. In the tank, after the mercury cools down, it flows into the recovery container of the mercury liquid through the liquid discharge pipe, which can realize the efficient separation of mercury and antimony.

[0011] With reference to the accompanying drawings, the specific implementation steps are as follows:

[0012] 1. Put the mercury-antimony composite ore in the blast furnace. This composite ore can be the mercury-antimony composite ore powder after pulverization, or the mercury-containing antimony concentrate or the antimony-containing mercury concentrate after washing.

[0013] 2. Use coal as raw material to heat the blast furnace to 1000~1200 degrees Celsius to...

Abstract

The invention relates to the technical field of ore dressing, in particular to a mercury-antimony smelting separation process. In order to overcome the defects that the mercury-antimony flotation separation process has complex separation process, new pollution production, high reclamation cost, high inter-containing content of separated products, low reclaiming rate and the like in the prior art,the invention adopts a smelting separation method to design a mercury-antimony composite ore smelting device. The invention adopts the technical scheme that the method comprises the following steps: firstly, heating mercury-antimony composite ore powder to 1,000 to 1,200 DEG C at high temperature by a blast furnace to obtain antimony trioxide and mercury vapor, reacting the antimony trioxide and coal by adopting a reflecting furnace, and reclaiming the antimony; and then, cooling the mercury to 30 to 50 DEG C by adopting a circular cooling device, and reclaiming the mercury; therefore, the reclaiming rate of the mercury is as high as 98 percent, the reclaiming rate of the antimony is as high as 96 percent, a plurality of devices in the prior mercury-antimony separation process are simplified to one device, and the mercury is reclaimed with zero cost and inter-containing substances are not produced during smelting the antimony.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a process for smelting and separating mercury and antimony. Background technique [0002] Mercury-antimony composite ore, as a mineral resource with huge value and widely existing in Shaanxi, Guizhou and other regions, is a complex and refractory mineral. At the same time, because mercury-containing emissions are highly polluting, if they cannot be recycled, they will cause huge pollution to the environment. , so its dressing and smelting process and comprehensive utilization have been widely concerned. [0003] The Chinese national invention patents that have been applied for include the following three methods: the mercury-antimony separation method of mercury-antimony composite ore, the mercury-antimony flotation separation method of mercury-antimony symbiotic sulfide ore, and the mercury-antimony flotation separation process. The first method is to use the flotati...
