Effect of different reagent regime on the kinetic model

Sep 01, 2019Rougher experiments were conducted on the sample with size fraction of −850 μm, using a 4.5 L Denver D12 flotation cell with 1800 rpm agitation speed. To perform flotation tests, after preparing the pulp with a defined solid ratio, the collector was added to the cell and mixed for 2 min; afterward, frother was also added and mixed for 30 sec.Get price


MPT paper NV

The flotation experiments were conducted in Denver laboratory flotation machine, D-12 with a cell volume Of about 3000 ml. The flotation studies were carried Out On graphite feed with eco-friendly single reagent Sokem 705C. Also, flotation tests using conventional reagents namely diesel as collector for graphite and pineGet price


Laureate Professor Graeme Jameson / Staff Profile / The

Results are given for a series of tests in which a 300 mm pilot-scale Jameson cell has been used in copper recleaner flotation, and for the flotation of a lead rougher feed. The results indicate that the production rate of solids, at the same superficial air velocity Jg, is higher than in conventional columns.Get price

Controlling H+ vs CO2 Reduction Selectivity on Pb

Nanocrystalline Pb films prepared by reducing PbO2 precursors have up to 700-fold lower H+ reduction activity than polycrystalline Pb foil electrodes but maintain the ability to reduce CO2. As a result, these "oxide-derived" Pb (OD–Pb) electrodes have higher Faradaic efficiency for CO2 reduction to HCO2– in aqueous solutions with almost no competitive H+ reduction. Even with Get price
