Description
Technical Field
The invention relates to a processing technology of polymetallic ore containing gold, zinc and iron.
Background
The auriferous zinciferous iron ore is positioned at the foot of the western Tianshan mountain of Xinjiang and at an Arrowla hot black metal ore-forming zone which is one of four iron ore concentration areas of Xinjiang, and geological exploration results show that the total amount of the ore resource is 1.49 hundred million tons, the gold grade of the ore is 0.70g/t, the zinc grade is 1.60 percent, and the total iron grade is 37.55 percent, so the auriferous zinciferous iron ore belongs to large-scale polymetallic ore. The gangue minerals in the polymetallic ore containing the gold, the zinc and the iron are mainly diopside and garnet, and are echeverite and tremolite. The metal minerals are of various types and have complex combination. The main metal minerals are magnetite, and the secondary metal minerals are sphalerite, pyrrhotite and limonite, and the trace and rare minerals are chalcopyrite, marcasite, pyrite, arsenopyrite and galena. The gold-containing minerals mainly comprise natural gold, silver gold ore and gold and silver ore. The gold mineral in the ore has a fine particle size smaller than 27 microns and is mostly in a wrapped state. The proportion of natural gold in the raw ore is only 44.44%, the content of sulfide-coated gold is 18.06%, and the balance is carbonate, silicate and limonite-coated gold. Through search, similar development examples of polymetallic ores containing gold, zinc and iron are not found in China, and no existing ore processing technology and processing technology can be used for reference. If the polymetallic ore containing gold, zinc and iron is developed and utilized, the processing technology and the processing technology suitable for the gold, zinc and iron ore containing gold need to be researched and developed according to the characteristics of the ore.
