Direct Preferential Flotation
Definition of this method is: separate
various helpful minerals in proper order. With its feature of high flexibility,
it can adapt the change of ore grade, especially for sulphide ore of high grade.
Xilin, Fankou, Lechang lead-zinc dressing plant of our country, and Laisvall
lead-zinc dressing plant of Sweden all adopt this method.


Combined Flotation Flowsheet
Firstly, get mixed concentrate through the
emersion of all useful minerals in ores; secondly, separate various helpful
minerals in sequence from mixed concentrate. These two steps together are called
part of amalgamate flotation Flowsheet. This process is suitable for treat raw
ores of complex structure, fine embedded grains, and low content of sulfide
mineral, which are in close symbiosis relationship. Because this process can
simplify process, reduce ores’ over grinding, so as to benefit separation.
Almarc Lead-zinc plant of former Soviet Union adopts preferential flotation this
process. By using this process, we can get higher index than preferential
flotation improve 10% of lead concentrate ore grade and 4.5% of zinc concentrate
ore grade, raise the rate of multipurpose utilization from 75.4% to 83.7%, and
double labor productivity. Qingchengzi zinc-lead ore dressing plant and
Xiaotieshan copper ore dressing plant of our country adopt this process.


Part of Amalgamate Flotation Flowsheet
We can get mixed concentrate by the
emersion of two useful minerals in ores together, then separate single
concentrate from the mixed concentrate. The two stages together are called part
of amalgamate flotation Flowsheet, which is the most widely used process in
production. It is quite economical to adopt this process when raw ores contain
low-grade nitrogen, copper-lead, copper-zinc, and lead-zinc.


Iso-flotability Flotation Process
According to minerals’ flotability in
ores, mineral assemblages of good, medium and worse flotability are separated
through flotation separation. Secondly, different helpful minerals are selected
out from all mixed concentrates, which is called iso-flotability flotation
process. For example, Huangshapinng lead-zinc ore dressing plant of our country,
and Zheskaz of former Soviet Union both adopt this process. Get Beneficiation,Ceramic Ball Mill,Ball Mill From http://www.ceramic-ball-mill.com
