pH/ORP measurement Copper flotation process
A high pH is important in copper ore processing to maximize this mineral's flotation properties. Most copper ore slurries tend to be acidic. Plants typically add lime to the slurry in the mill or floatation circuit, increasing its alkalinity. A typical copper operation contains many flotation cells, often with a pH sensor in each cell.

Flotation of Copper Ores
The first pneumatic-flotation plant in this country was erected by me in February 1914 for the National Copper Company at Mullan, Idaho, a description of which has already been published. The results were fully up to expectations from the very start. This plant consists of 8 rougher and 2 cleaner cells and treated 500 tons per 24 hours.

Thickening and filter capacity is selected for a 10 to 1 ratio of concentration as would be the case when treating a 3% copper ore with the copper mineral being chalcopyrite. In such case it would be necessary to filter 50 to 55 tons of concentrates each day. The use of a mineral jig or flotation unit cell in the grinding circuit is recommended.
