Embodiment 1

[0033] The ore processed in this embodiment contains 1.16% lead, 2.85% zinc, 0.47% antimony and 4.40% carbon.

[0034] The non-decarbonization priority flotation process is adopted, specifically, the process of first roughing, two sweeps and three refinements is used to preferentially flotation lead and antimony, and the tailings of lead and antimony are flotationed by a process of one rough, two sweeps and three refinements to flotation zinc. Specifically include the following steps:

[0035] (1) Rough selection of lead and antimony: add lime 1500g / t, zinc sulfate 800g / t, sodium sulfite 400g / t, lead nitrate 600g / t, butylammonium black medicine 300g / t, ethionyl 40g / t, terpineol oil in sequence 40g / t, lead-antimony coarse concentrate is obtained by flotation;

[0036] (2) Sweeping of lead and antimony: Sweep twice for the tailings of the roughing of lead and antimony, add 400g / t of zinc sulfate, 200g / t of sodium sulfite, 400g / t of lead nitrate, and 150g of ammonium butyl ammon...

Embodiment 2

[0052] The ore processed in this embodiment contains 1.16% lead, 2.85% zinc, 0.47% antimony and 4.40% carbon.

[0053]The pre-decarbonization priority flotation process is adopted, specifically, the primary roughing flotation carbon is adopted, and the floating carbon tailings are subjected to a process of first roughing, two sweeping and three refining processes to preferentially float lead and antimony, and for the lead and antimony secondary sweeping tailings, one-stage Coarse two-scanning and three-finishing process for flotation of zinc. Specifically include the following steps:

[0054] (1) Decarbonization: Put the grinding product into the flotation cell, add carbonaceous collector kerosene 100g / t, terpineol oil 40g / t for decarbonization;

[0055] (2) Rough selection of lead and antimony: after decarburization, add lime 1500g / t, zinc sulfate 900g / t, sodium sulfite 450g / t, lead nitrate 700g / t, butylammonium black medicine 160g / t, ethylsulfide nitrogen 50g / t , Pinitol o...

Abstract

The invention provides an ore dressing method for lead, zinc and antimony ore containing carbon. The method comprises the following steps of decarburization in advance, lead and antimony coarse separation, twice lead antimony scavenging, three-time lead and antimony fine separation, zinc coarse separation, twice zinc scavenging and three-time zinc fine separation. Kerosene is used as carbon substance collecting agents, lime is used as regulating agents, zinc sulfate and sodium sulfite are used as zinc inhibiting agents, lead nitrate is used as antimony activating agents, ammonium dibutyl dithiophosphate and diethyldithiocarbamate are used as lead and antimony collecting agents, copper sulfate is used as zinc activing agents, butyl xanthate is used as zinc collecting agents, and terpenic oil is used as foaming agents. The ore dressing method has the advantages that the technical flow processes of decarburization in advance, preferential lead and antimony flotation and zinc re-separation are adopted for processing lead, zinc and antimony ore containing carbon, and the actual problems of great separation index fluctuation, great medicine consumption and high production cost of the existing technical flow process are solved.

Description

1. Technical field [0001] The invention belongs to the technical field of mineral flotation separation, in particular to a beneficiation method of carbon-containing lead-zinc-antimony ore. 2. Background technology [0002] my country is rich in lead-zinc-antimony mineral resources, but the high-grade, easy-to-mining and easy-to-process ores are decreasing and facing depletion; low-grade, difficult-to-mine and complex ore properties have gradually become an important source of raw materials for lead-zinc-antimony ore dressing. Therefore, the development of low-grade, complex refractory lead-zinc-antimony ore beneficiation technology has become an important research topic, and it is also an important guarantee for improving the utilization rate of refractory ore resources. The beneficiation process of lead-zinc-antimony sulfide ore mainly adopts mixed flotation process and priority flotation process. There are many studies on the flotation of lead-zinc ores at home and abroad...
