Flotation
Machine
can be used to separate nonferrous metal, ferrous metal, heavy
metal, nonmetallic mine, chemical material and recycling minerals. Each chute
can inhale gas, sink magma, separate. No assiting equipments are required, and
Flotation Machine must be levelly installed. Flotation Machine is easy to change
the flow chart. The cycling way of magma is very reasonable. Flotation Machine
can reduce the impurities to a great extent. There is automatic equipment on the
magma surface, easy to adjust. The impeller also owns the upper and lower
retroversion blade. The upper one makes the magma cycle upward, while the lower
one makes the magma cycle downward.


Flotation machine has many same characteristics with other machines, such as
reliable working, wear-resisting, low power consumption, simple structure and
low price. It also should have the special requirements like followings to meet
the flotation requirements:


1. Well inflatable role: Flotation machine must guarantee a certain of air
amount be absorbed or pressed into the ore pulp and disperses in all the slot.
For the air can be dispersed more finer and more uniform, the contact between
the ore grains and air bubbles will be more so that the flotation efficiency can
be higher.


2. Mixing role: Flotation machine should have well mixing role to make the
ore grains suspension and distributed in all the slot uniformly. At the same
time, the machine can promote the solvation of some hard dissolved agentias,
which is in favor of the full function between the agentias and ore grains.


3. Circular flow function: In flotation machine, the circular flow of ore
pulp can make more contact between the ore grains and air bubbles. Get Beneficiation,Ceramic Ball Mill,Ball Mill From http://www.cement-ball-mill.com

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. beneficiation,Mineral Processing,rotary kiln http://www.dryballmill.com
