For the development of Yunnan Chihong Co. deep lead zinc resources, Beijing Research Institute of Mining and Yunnan Chihong Co. creatively developed "and the like may be floating - Asynchronous selected from lead - zinc sulfur asynchronous mixture selected from - Lead-zinc-sulfur separation-lead-zinc-zinc mine does not de-sludge vulcanization potential control flotation" new technology, and successfully applied to the beneficiation process of complex refractory lead-zinc sulfide oxidation mixed ore, the technology has made a breakthrough.
1. According to the close relationship between lead sulfur and zinc-sulfur, the lead-zinc sulfur is divided into two parts according to the principle of floatability: the “lead-sulfur†part and the “zinc-sulfur†part, for the first time, the two processes of asynchronous and equal floatation The core technologies are organically combined to form a floatable asynchronous flotation and mixing process structure, which becomes the backbone process of sulfide ore flotation; the use of effective targeted collectors ensures gold in lead, zinc, sulfur, silver and antimony. The genus is recycled to the maximum extent, ensuring the separation of lead sulphur at low pH, which creates the necessary conditions for the effective flotation of subsequent oxidized ore.
2. The new technology of lead-zinc-free ore-free desulfurization and flotation flotation solves the problem that the lead-zinc oxide minerals and gangue minerals in the ore are both carbonate minerals and high degree of muddyness, and it is a breakthrough in obtaining the technical index of mixed ore flotation. Key technologies for sexual progress.
The final mineral processing product has a simple structure and is easy to operate and manage. The technology has reached the international leading level as a whole.
