Separation of oxidized lead-zinc ore production line technological process. The separation of lead-zinc ore is mainly flotation, and the combined process of gravity separation and beneficiation metallurgy can also be used. Due to the uneven dissemination granularity of ores in lead-zinc ores, different ores should have corresponding grinding and flotation processes. Separation of lead and zinc oxide ores What is the process flow of the lead-zinc ore dressing production line? Lead zinc ore dressing equipment manufacturer pin The seller Yingkuang Machinery told you.
The separation of lead-zinc ore is mainly flotation, and the combined process of gravity separation and beneficiation metallurgy can also be used. Because the embedded particle size of lead-zinc ores is uneven, different ores should have corresponding grinding and flotation processes.
The process flow of separation and flotation of lead-zinc ores includes:
(1) Preferential flotation process. This process is often used in lead-zinc mines.
(2) Part of mixed flotation process. There are also many applications
(3) Full mixed flotation process
(4) Heavy medium preselection - lead-zinc priority flotation process in turn.
(5) Heavy medium pre concentration flotation gravity concentration combined process; For ores containing lead, zinc and tin, heavy medium beneficiation method is used for pre concentration, and about 35 waste rocks are discarded; The flotation adopts the process of stage grinding and stage separation to select lead and zinc concentrates in turn; After the flotation of zinc tailings to remove iron sulfide, the tin concentrate is selected by turning the bed.
(6) In the equifloatable flotation process, the minerals to be recovered are divided into easy flotation and difficult flotation parts according to the principle of equal floatability, and mixed flotation is carried out separately to obtain mixed concentrate, and then separate separate concentrates of useful minerals in turn.
(7) Asynchronous mixed flotation process. In the whole process of mixed flotation of lead and zinc, various factors such as pulp pH, easing and activation conditions, and collector action intensity are controlled artificially and in stages. Concentrated minerals give full play to their unique floatability under their respective suitable flotation conditions asynchronously, so that high beneficiation indexes can be obtained.
Lead sulfide, lead oxide, zinc sulfide zinc oxide Preferential flotation process. Lead oxide and zinc oxide are usually sulfurized with vulcanizing agent before flotation, and then flotation is carried out.
The common methods for the treatment of lead and zinc oxide ores include: (1) sulfuration with sulfurizer, flotation of lead oxide with xanthate, and flotation of zinc oxide with amine; (2) The zinc oxide minerals were first heated by steam, then activated by copper sulfide, and then collected by xanthate; (3) For lead-zinc oxide ores that are not suitable for flotation treatment, the combined process of heavy medium separation – Wiltz process – smelting process separation – smelting can be used.
The main operating equipment of Xingkuang Machinery Co., Ltd. includes: mines Crushing equipment Grinding equipment, washing equipment, sintering equipment, tailings treatment equipment. The whole beneficiation production line mainly includes: lead-zinc ore beneficiation production line, potassium feldspar Contract operation of flotation process, gravity separation process and magnetic separation process production lines such as beneficiation production line, fluorite ore beneficiation production line, gold ore beneficiation production line, copper ore beneficiation production line and silver ore beneficiation production line.
