A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two or more parallel ...

Figure 38 shows its place in the circuit at the MclntyrePorcupine mine, Ontario. The flotation machine and its use in the circuit have been patented in several countries. The unit flotation cell prevents the accumulation of free gold in a ball mill classifier circuit by removing coarse gold as soon as possible.

The mixed flotation process is a commonly used process in the flotation of polymetallic sulfide ores. First, all the useful minerals are mixed and floated, and then the useful minerals in the mixed concentrate are separated one by one. This process is suitable for useful minerals grade comparison. Low (more gangue content) and useful minerals ...

This tank is there to allow the reagents time to become well mixed with the ore and condition it for recovery. The slurry flow then enters the feed end of the flotation cells. The slurry at this point is called the HEADS of the circuit. The mineral is then separated and flows over the overflow into a trough called a flotation cell LAUNDERER.

water usage. The crushed ore is transferred to a semiautogenous (SAG) mill or ball mill where the ore is further reduced in size. Water is added to the ball mill, in which a slurry that usually contains from about 20 to 55 percent solids is produced (Singh, 2010; International Mining, 2011) (see fig. 2). The

SAG mills, rod mills and ball mills are the classical pieces of grinding equipment employed in gold recovery plants. There is an increasing trend to employ SAG mills (semiautogenous mills) in place of secondary and tertiary crushing and primary grinding. The most common type of rod mill is the overflow mill. There are two typed of ball mills used.
