A slight change in performance can have a far-reaching impact on the productivity and profitability of your operations. One key area that needs to be focused is the performance of a flotation circuit. Optimal mineral recovery in a flotation circuit depends on the capacity to adapt to metallurgical variability in the ore being processed.
Laboratory flotation experiments confirmed the observed poor plant flotation response when the corrosiveness of recycled process water increased. Total dissolved solids (TDS) was proven to be a reliable online parameter for the corrosiveness of the recycled process water and was inversely proportional to the pentlandite recovery.

STRUGGLES IN FLOTATION Flotation is known as a complex process that is affected by a lot of factors. These factors may be related to the circuit design and how the flotation plant is operated. Different process variables are affecting the circuit performance, for example the particle size, slurry density, flow rates,
Since these criteria generally cannot be met, a large amount of the slag produced as a by-product is stored as waste in the plants (Zheng and Kozinski, 1996). The slag is rather than simply "waste". It is another complex resource for metals. Therefore, it is processed by flotation after crushing-grinding by smelting plants.
