Numerous mineral resources and rich reserves, according to the statistics of 45 kinds of main Mineral Resources, the ore reserve total value in China occupies
The world the 3rd accounts for global 14.64%, is only second to the U.S. and the former Soviet Union.Although total amount is abundant, mineral resources are occupied per capita
Amount but only has the 58% of world average level, occupies the 53rd, the world.In addition to this, there is also difficult ore dressings, poor for China's mineral products
The problems such as mine is more, and deposit scale is less than normal, and the rate of recovery is low and waste is serious.Pulp density has extremely in entire ore-dressing technique
Important role, it directly influences every technical-economic index of ore-dressing technique.Therefore, ore pulp is got hold of in ore dressing process
Concentration is particularly important.
Influence of the pulp density to ore-dressing technique is embodied in the following aspects:
1, mineral recovery rate；This point be mainly reflected in floatation process, in the flotation of various mineral, pulp density and return
Yield has certain regularity.When ore pulp is very dilute, the rate of recovery is lower, with gradually increasing for pulp density, the rate of recovery
It gradually increases, and reaches maximum value.It but is more than after best pulp density, the rate of recovery reduces again.The reason is that due to pulp density mistake
It is high or it is too low all flotation device venting condition can be made to degenerate, so production in should hold mineral concentration appropriate.
2, final concentrate quality；In diluter ore pulp when flotation, concentrate quality is higher, and the flotation in denseer ore pulp
When, concentrate quality just declines.
3, the production capacity of flotation device；With increasing for pulp density, flotation device presses the production capacity for the treatment of capacity production
Increase.
4, the ore dressing time；When pulp density is higher, flotation time be will increase, and is conducive to improve the rate of recovery, be increased floating
Select the productivity of machine.
Currently, measurement of concetration mode is artificial field sampling in dressing plant's ore-dressing technique, concentration value is calculated in measurement.
Manual measurement speed is slow, and measurement accuracy is not high, and along with measurement point is more, measurement point dispersion is greatly lowered production efficiency, adds
Labor intensity of operating staff is weighed, while operator enters the security risk height of field sampling.
