The results revealed that rheology which is caused by pulp density played a key role in flotation performance. The decline in density from 40 wt to 20 wt increased the nickel and copper recoveries from 70.7 to 79.5 and 82 to 85.4 respectively in the artificial mixture 11.
Sep 24 2018 The optimum solids content of the pulp is 35 because by increasing the pulp density more particles report to the concentrate and increase copper recovery also reducing concentrate grade. Drawing on the literature in the flotation area a dependence of mineral recovery upon pulp density can be seen 24 26 32 .
Mar 19 2017 PROCESS CONTROLS. Automatic controls are usually provided throughout modern plants to measure and control pulp flow pH and density at various points in the circuit. Feed and density controls are relatively common and the newer installations are using automatic pulp level controls on flotation machines and pump sumps.
When the ore is roughed the pulp concentration is 25 35 and the flotation fine particles and the ore with high mud content is 10 20. When the flotation density of the mineral the material particles are larger the use of thick pulp. When the flotation density is small the mineral of fine grain and slime material is used thinner pulp.
Apr 13 2016 Copper Sulfide Flotation Circuit. The pulp from the Conditioner is treated in a 10-cell Sub-A Flotation Machine and a 4-cell Sub-A Flotation machine. Sometimes conditioners are not provided however their use insures that reagents are thoroughly mixed into the pulp ahead of flotation.
flotation chemical and equipment operating conditions 40. They can be effectively used to evaluate variables affecting the flotation process 16. Particle size reagent type and dosage air flow rate pulp density and wash water rate are some of the influential pa-rameters on flotation process efficiency 8 28 33 34 39. Although copper .
Despite that the appliance has been applied to various flotation froths showing that the shear rate of the flotation froth was less than 4 s 1 much less than that in pulp phase of which the average has been believed to be around 100 or 160 s 1 quantitatively confirming that flotation froth provides a much more tranquil environment i.e. less turbulence than the pulp phase for further product concentration.
Nov 01 2011 Froth flotation is a physicochemical process that has been used for more than a century in the concentration of copper sulphide minerals Herrera-Urbina 2003. This process is based on the wettability of mineral particles to recover the mineral species of interest and depress unwanted gangue.
The most suitable ore pulp concentration during the flotation process is related to the ore property and the flotation processing conditions. The general rules as flow 1 Pulp Density. The mineral with large flotation density uses a thicker slurry while the mineral with a small flotation density
As the common mineral processing process the froth flotation process is widely used in the concentrator. Because the froth flotation process is strict with grinding fineness pulp density flotation reagent the flotation plant operators must inspect the flotation conditions during the operation of the flotation machine.
The pulp concentration is 25 35 the flotation fine grain and high mud content ore is 10 20. When the mineral flotation density is large the material particle is large then uses the thick pulp. When the flotation density is smallfine and muddy materials of minerals are used in the dilute pulp.
The Acoustic transducers are not affected by the density changes and conductivity changes to the PulpSlurry providing repeatable accurate readings. The FloLevel system also provides additional process feedback on Froth Height Froth Density contained mineral and Froth Flow Rate to improve each Flotation Cells efficiency.
