Experiment on selecting lead and zinc using precision micro bubble flotation machine in a smelter in Shandong province
|project||Element Name||productivity%||Feed grade||Concentrate grade||Enrichment ratio||tailings grade||rate of recovery%|
Lead selection: The lead grade of the raw ore is 7.22%, the lead grade of the concentrate is 51.42%, and the recovery rate is 77.79%; At the same time, the concentrate has a silver grade of 1159.61g/t and a recovery rate of 6649%. Both lead and silver have been well recovered. Copper and zinc control are also ideal. A precision micro bubble flotation machine can directly produce concentrate.
Zinc selection: A precision micro bubble flotation machine can directly produce zinc concentrate with a grade of 43.54% and a recovery rate of 75.83%.
