Problems solved by technology

[0004] In the current process, lime needs to be added many times to suppress pyrite and adjust the pulp. There are a lot of heavy metal ions in the pulp. Due to the excessive addition of lime, the cost of tailings water treatment in the latter stage increases, and the cost of the concentrator is virtually increased. Production costs and environmental protection costs. At the same time, the current process has a low enrichment ratio of indium in the ore and a large waste of ore, which is not conducive to the long-term development of the concentrator and the development of resources.

Embodiment 1

[0023] Such as figure 1 Shown, a kind of process that selects sphalerite from high-iron sulfide ore:

[0024] ① Grinding: after ball milling the lead flotation tailings, enter the mixing tank;

[0025] ②Zinc roughing Ⅰ: add 1kg / t of lime, 600g / t of copper sulfate, and 76g / t of collector into the mixing tank according to each ton of raw ore, and select zinc rough concentrate and primary tailings; the collector It is Z-200 collector;

[0026] ③Concentration: The above-mentioned rough zinc ore is subjected to concentration I, and then concentration II is carried out after concentration I to obtain zinc concentrate. Ⅰ Reelection;

[0027] ④Primary tailings treatment:

[0028] a. The primary tailings from zinc roughing are carried out to sweeping I; the foam product produced after sweeping I is returned to roughing I for re-election.

[0029] b. After sweeping, add copper sulfate 200g / t and collector 28g / t to carry out zinc roughing II; the collector is Z-200 collector.

Abstract

The invention relates to mineral processing process, in particular to process for selecting marmatite from high ferric sulphide ore. The process includes the steps of ore grinding, roughing I, fine selecting and primary tailing disposing. The process for selecting marmatite from high ferric sulphide ore can effectively reduce usage of lime, achieves the purposes of energy conservation and environment protection, improves recovery rate and grade of the marmatite, can well separate the marmatite from the high ferric sulphide ore, improves indium-containing grade, and achieves comprehensive utilization effects of ore resources.

Description

technical field [0001] The invention relates to a beneficiation process, in particular to a process for beneficiating sphalerite from high-iron sulfide ores. Background technique [0002] Sulfide ores refer to unoxidized or slightly oxidized ores in sulfide deposits. This technology mainly deals with underground lead-zinc mixed ore. The symbiosis relationship between lead and zinc in the raw ore is complicated, the embedded particle size is different, and the content of sulfur and iron is high. The main metal minerals are pyrite, sphalerite, galena, lead carbonate, lead vanadium, smithsonite and so on. Gangue minerals are mainly iron hydroxide, manganese hydroxide, calcite, clay minerals, weathered silicate, quartz, mica, etc. Lead and zinc mainly exist as sulfides. [0003] The current process adopts the traditional priority flotation process, adding zinc sulfate emulsification to high alkali pulp to suppress zinc and levitate lead, copper sulfate activator, and using is...
