Details >Flotation Circuit. Real-time density measurement can help to verify changes in the slurry from the grinding circuit to the flotation cells. The effect of flotation feed density on metallurgical performance has been investigated. Results of test work have shown that the pulp density affects key parameters of the flotation process in both the pulp and froth phases ( Runge et al, 2012 ).
Details >Mining Comminution and Beneficiation In most mines, the grinding circuit is either the largest or second largest capital investment With the emergence of low grade – high tonnage operations, this is especially true because economics dictate the use of the largest milling equipment to …
Details >7.5.2 Circuit Operation. Grinding circuits are fed at a controlled rate from the stockpile or bins holding the crusher plant product. There may be a number of grinding circuits in parallel, each circuit taking a definite fraction of the feed. An example is the Highland Valley Cu/Mo plant with five parallel grinding lines (Chapter 12). Parallel mill circuits increase circuit flexibility, since individual units can be shut down or …

Details >Each line has an independent grinding circuit, with two ball mills and three hydrocyclones batteries. The product from the grinding circuit feeds a desliming circuit, which produces an underflow that is directed to the flotation circuit feed, and an overflow which forms part of …
Details >Thus, to optimise flotation recovery and grade it is usually best to grind to a fine size. This requirement needs to be balanced by the cost of grinding finer and the revenue that results from an increase in grinding throughput, which often results in a coarsening of the flotation feed. This paper.
