After carrying out a froth flotation separation, the products are as shown in Table 1. Using this data, calculate: (a) Ratio of concentration (b) % Metal Recovery (c) % Metal Loss (d) % Weight Recovery, or % Yield (e) Enrichment Ratio Table 1: Grade/recovery performance of a hypothetical copper ore flotation process.
The rougher flotation behavior of a sulfidized copper ore was studied by a series of batch flotation experiments. Response surface modeling based on central composite design was applied to optimize and evaluate the effects of collector, depressant and frother dosages, solution pH and agitation rate on the copper recovery.
In this paper, the flotation behaviour of nickel-copper ores processed in the Sudbury area is discusse~ with emphasis on the effect of oxidation on individual minerals, pnmarily pyrrhOlite. In general, moderate oxidation of a freshly ground ore promotes the flotability of all principal sulphides in the ore leading to a bulk flotation concentrate.
Impact of operation parameters on designing flotation cells (gas hold-up, superficial gas velocity, bubble size distribution and orifice type, etc.); ... (RNN) method were used to predict the copper ore flotation indices, i.e., grade and recovery within different operating conditions. The model input parameters including pulp pH and solid ...
For some time past the company has been experimenting with a view to finding the best method of concentrating the sulphide ore before smelting. The first test-mill consisted of two sets of rolls, one Chilean mill, one Hardinge conical mill 6 ft. diam. by 12 in. cylinder, Richards hindered-settling classifier, Deister tables, some kind of ...
