Effect of Water Quality on Froth Stability in Flotation
In flotation, the froth structure and froth stability are known to play a significant role in determining the mineral concentrate grade and recovery. Froth stability is not only depending on the type and amount of the frother used, but also on the amount and nature of the suspended particles. Furthermore, there are other parameters such as quality of water which are not yet fully understood. In...
متن کاملEffect of operating parameters on desulphurization of mine tailings by froth flotation.
A site-specific study is carried out to assess the suitability of froth flotation for desulphurization of reactive mine tailings at the Musselwhite Mine, Northern Ontario, Canada, to prevent acid mine drainage (AMD). The results from pilot scale flotation tests on an Outokumpu flotation unit are presented, which confirm that froth flotation is effective to reduce sulphide contents of tailings. ...
متن کاملFroth flotation of phosphate rock
The development of froth flotation is traced from its earliest-known use through the discoveries leading to the present knowledge of the science. The factors influencing the flotation of non-sulfide and non-metallic minerals are discussed, and the machines used in commercial flotation operations are described. Experimental work on the flotation beneficiation of phosphate rock is presented as an...
متن کاملDynamic Modeling and Real-Time Monitoring of Froth Flotation
A dynamic fundamental model was developed linking processes from the microscopic scale to the equipment scale for batch froth flotation. State estimation, fault detection, and disturbance identification were implemented using the extended Kalman filter (EKF), which reconciles real-time measurements with dynamic models. The online measurements for the EKF were obtained through image analysis of ...
متن کاملRecovery of Copper from Copper Slag and Copper Slag Flotation Tailings by Oxidative Leaching
Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings. Hydrogen peroxide was determined to be the best lixiviant. Thus, copper and iron extractions were ...
