Table 1: Grade/recovery performance of a hypothetical copper ore flotation process. Product % Weight % Cu Assay Feed 100 2.09 Concentrate 10 20.0 Tailings 90 0.1 (a) From Table 1, the Ratio of Concentration can be calculated as F/C = 100/10 = 10. If only assays are available, the ratio of concentration equals (20 – 0.1)/(2.09 – 0.1) = 10 ...

Another method to separate Pb from Cu is in depressing the lead away from the copper to float. Here, three batch cleaner tests were performed with additional depressants to reject more lead from the copper flotation concentrate. The baseline test utilized no MBS depression in the rougher circuit to maximize copper recovery, but …

1.1 The Flotation Process. Flotation with is one of the most important and widespread concentration methods, which is based on exploitation of the differential …

This project is a "Copper flotation" project with some Moly (<200ppm). The chosen scale-up was 2.5 while The Book calls for on copper 2.1X. Without have access to the complete metallurgical testwork data and results I'd say 2.5X was the extra chosen to factor in Moly recovery which The Book calls for 2.6X.

Dewatering and water recycling are therefore essential for mineral processing operations. Copper is one of the most widely used metals in various industries. About 20 million tons of copper were produced worldwide in 2019 (Esmaeili & Aslani, 2019). Large amounts of tailings are produced when copper minerals are concentrated …
