Gold Flotation Mineral Processing Metallurgy

Where a high sulphide recovery is demanded flotation methods are now in general use but in the days before flotation was known a large part of the world s gold was recovered by concentrating the gold bearing sulphides on tables and smelting or regrinding and amalgamating the product Though the modern trend is away from the use of tables

Jameson cell Wikipedia

The high intensity of the Jameson Cell means that it is much shorter than conventional column flotation cells see Figure 1 and it does not require air compressors to aerate the suspension of ground ore particles and water known as a slurry or pulp in the flotation cell The lack of a requirement for compressed air and the lack of moving parts means that power consumption is less than for
