Aug 15 2020nbsp018332the coppercitratethiosulfate system has a similar extraction capacity for gold from freemilling gold ores compared to the traditional cyanidation the coppercitratethiosulfate system has some advantages over cyanidation such as green nontoxic and shorter leaching time
This paper optimizes the process parameters spindle speed feed and depth of cut for beryllium copper alloy c17200 in conventional vertical milling operation using a 6 mm carbide end mill the experiments were conducted by using response surface methodology rsm face centered central composite design
Milling depth has a great influence on cutting force when milling speed is about 2400 rmin the axial milling depth is 03 mm and the feed is 02 mmr which can obtain small milling force and lower tool temperature and further extend the life of pcd tool
