Mercury Ore Beneficiation Production Line and Process Solution

1. Program Overview

This program provides professional mercury ore beneficiation production line and process solution according to the characteristics of different types of mercury ores. According to the structure type and embedded characteristics of mercury ore, gravity separation, flotation or combined process is adopted to recover mercury concentrate efficiently and realize the maximum utilization of resources.

2. Characterization of raw materials

Main types and characteristics of mercury ore:

• Lumpy mercury ore: mercury minerals are concentrated and distributed, with obvious boundaries with veins and large specific gravity difference.

• Mottled mercury ore: mercury minerals are distributed in the form of spots, partly coexisting with veins.

• Leached mercury ore: fine grains of mercury minerals are leached, and closely symbiotic with veins and stones

• Physical properties: cinnabar specific gravity 8.1-8.2, bright color, good natural floatability.

3. Mercury ore beneficiation process design

Massive mercury ore treatment process
After rough crushing, the raw ore is pre-enriched by hand or gravity separation. After pre-enrichment, the ore is finely crushed and screened, and then gravity separation is carried out by jigger or shaking table to finally obtain mercury concentrate.

Treatment process of speckled mercury ore
After crushing and screening, the raw ore is first roughly sorted by gravity separation process, discarding a large amount of tailings. The rough concentrate of gravity separation is then processed by grinding to fully dissociate the mercury minerals, and finally selected by flotation process to obtain high-grade mercury concentrate.

Treatment process of leached mercury ore
After crushing, the raw ore enters the ball mill for fine grinding to fully dissociate the minerals. The milled products are classified, and the qualified granularity enters the flotation system, and by adding flotation chemicals, the flotation machine is used for sorting, and finally the mercury concentrate is obtained.
