pH/ORP measurement Copper flotation process
pH/ORP measurement Copper flotation process

A high pH is important in copper ore processing to maximize this minerals 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.

Froth Flotation an overview ScienceDirect Topics

Copper or metal recovery percentages of the flotation circuits of a copper mine/mill are extremely important. For example, it is estimated that for a plant processing 50,000 tonnes of ore containing 1 copper per day, increasing the copper recovery from 86 to 87 of that contained in the ore could increase revenues by approximately $4 million annually.

Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding a process knownminution so that the various minerals exist as physically separate grains. This process is known as liberation. The particle sizes are typically less than 0.1 mm 100 µm, but sometimes sizes smaller than 710 µm are required. There is a tendency for the liberation size of the minerals to decrease over time as the ore bodies with coarse mineral grains that can be separated at larger sizes a
