Lead-zinc ore beneficiation rich integration generally go through in order to concentrate smelting of lead, zinc and metal products. Metallurgical testing of ore processing technology, geological exploration work is an important part of the evaluation of ore deposits can be commercialized an important basis for the development, so the process must be carried out geological prospecting ore optional test. In the detailed investigation or Chukan stage should generally be made optional preliminary laboratory tests or detailed survey stage in Chukan generally do detailed test optional. When the complex composition of the ore material, there are huge value of comprehensive utilization of medium-sized, large or of new types of ore deposits, in addition to the detailed test optional, but necessary, to do the expansion of laboratory tests. When certain types of ore beneficiation methods are not qualified or unable to concentrate product monomer separation, but also for laboratory smelting tests. Optional carrying ore prior to the test substance should first be constituents of the ore deposit, divided ore type, to identify elements of occurrence, identification of minerals, ore texture and structure, dissemination size characteristics, develop a reasonable process for the beneficiation tests provided basis.
By type of lead-zinc ore industry, is based on the natural type of ore, according to varying degrees of oxidation into sulphide ore ore (lead or zinc oxide ratio <10%), oxidized ore (lead or zinc oxide ratio> 30%), mixed ore (lead or zinc oxide ratio of 10% to 30%). Press ore useful components can be divided into lead ore, zinc ore, lead-zinc ore, copper ore, lead, zinc, lead and zinc sulfide ore, lead, zinc sulfide copper ore, tin ore, lead antimony ore, zinc and copper ore and so on. Press ore texture and structure can be divided into disseminated ores, dense block of ore brecciated ore, banded ore veinlet ores.
Metallurgical sector needs to be elected by ore type, sub-mining, sorting (MCC), the geological profile in the circle on the can, and can cope with the adjacent section is connected, it should ring out of its distribution range, were calculated reserves.
Lead and zinc beneficiation tests, according to the different types of ore, then select a different processing methods. Sulphide ore flotation method commonly used. Oxidized ore flotation flotation or re-election with the United dressing, or roasted sulphide flotation, re-election or re-treated with sulfuric acid flotation. For metal-containing multi-lead-zinc ore, usually with magnetic - floating, heavy - floating, heavy - Magnetic - Floating other joint processing methods.
