Description
Technical field
The invention belongs to mineral manufacture fields, and in particular to a kind of separation of Cu and Co choosing of copper cobalt sulfide ore of the pyrite containing cobalt
Mine method.
Background technology
China's cobalt resource is very short, is one of highest non-ferrous metal of external dependence degree, and cobalt is mainly the companion of copper, nickel minerals
Production-goods source, according to statistics, 50% cobalt derive from the byproduct of nickel, and 44% cobalt is from copper and the byproduct of other metals, only
There is 6% cobalt to come from primary cobalt ore.China's cobalt metal is essentially from the copper cobalt ore or cobalt oxide ore of import, therefore separation of Cu and Co
Technology becomes the key that cobalt resource makes full use of.
Flotation is to sort one of the major way of copper cobalt sulfide ore stone, and conventional floatation process includes：1) bulk flotation, i.e.,
Copper mineral and cobalt mineralss are sorted in bulk concentrate together, bulk concentrate carries out copper cobalt mineralss point as final products or again
From；2) diffeential floatation, i.e., first flotation copper mineral flotation cobalt mineralss again, finally respectively obtains copper concentrate and cobalt concentrate；3) ion is floating
It selects, i.e., collecting agent is added in copper cobalt mixed liquor after leaching, collecting agent forms indissoluble substance with copper cobalt ions, recycles indissoluble
The difference of the Surface Physical Chemistry property of substance sorts copper and cobalt.
Part China-invested enterprise of Congo (Congo-Kinshasa) has had ripe sulfidation roasting and hydrometallurgy production line, copper sulfide cobalt mixed
Close concentrate and obtaining metal copper plate and cobalt crude product after metallurgical technology, the former market goods locally and the latter needs to transport depth back home
Processing is to realize the maximization of economic benefit, but metallurgical technology can cause during handling copper sulfide cobalt bulk concentrate
The loss of the copper cobalt rate of recovery.
Congo's copper cobalt sulfide ore is a mine being developed, is passed by line positioned at along Congo (Congo-Kinshasa) and Zambia
The Lu Feili copper mine bands of spread, copper and cobalt resources are abundant.Copper mineral in ore is mainly chalcopyrite, is secondly vitreous copper, spot copper
Mine, covellite and a small amount of native copper etc.；Cobalt mineralss are mainly carrollite, secondly cobalt with isomorph preservation in pyrite,
Distribution law reaches 45% or more.Currently, ore dressing plant mainly produces copper cobalt bulk concentrate, bulk concentrate needs to transport deep processing back home
Or transport processing after roughing back home again on the spot, bulk concentrate copper cobalt grade is relatively low, occurs metal in subsequent processes
The problems such as coefficient of valuating is low, ton amount of metal transportation cost is high, the rate of recovery is lost, metallurgical system cost input is high.
Therefore, seek technical feasibility, the separation of Cu and Co technology of economical and efficient becomes particularly important.
Invention content
The present invention mainly produces copper cobalt bulk concentrate for Congo's copper cobalt sulfide ore mine concentration and provides one
The separation of Cu and Co beneficiation method of kind copper cobalt sulfide ore.Specific technical solution is as follows：
