Effect of Ultrasonic Pre-Treatment and Aeration on Flotation Separation of Chalcopyrite from Pyrite
In this paper, the effect of ultrasonic pre-treatment and aeration on the flotation separation of chalcopyrite from pyrite was investigated at different amounts of potassium ethyl xanthate (KEX), as a collector, and pH values. Artificially-mixed samples of chalcopyrite and pyrite were subjected to flotation studies to understand the effect of aeration with or without ultrasonic tre...
متن کاملWEAR RATE PREDICTION OF GRINDING MEDIA USING BPNN AND MLR MODELS IN GRINDING OF SULPHIDE ORES
Nowadays steel balls wear is a major problem in mineral processing industries and forms a significant part of the grinding cost. Different factors are effective on balls wear. It is needed to find models which are capable to estimate wear rate from these factors. In this paper a back propagation neural network (BPNN) and multiple linear regression (MLR) method have been used to predict wear rat...
متن کاملEffect of grinding time on flotation recovery of copper smelting slags in Bardaskan district
Copper smelting slags are hard materials. Therefore,to recover their copper by flotation method, grinding should be carried out to obtain optimal particle size. Copper smelting slags in the Bardeskan district, with work index of 16.24 kwh/st, were grinded for 65 minutes to reach an acceptable degree of freedom for the flotation tests, with particle size of 80%, smaller than 70 μm. With this gri...

15 صفحه اولTHE EFFECT OF GRINDING TIME ON THE SPECIFIC SURFACE AREA DURING INTENSIVE GRINDING OF MINERAL POWDERS
Abstract: the changes of BET surface area of a mineral substance during intensive grinding process. Validity of the proposedmodel was tested by the experiments performed using a natural chalcopyrite mineral as well as the published data. Itwas shown that the model can predict the experimental results with a very good accuracy and can be used to predictwhat may happen under the similar experimen...
