Optimizing Flotation Cells. H ow a flotation cell works . Flotation Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry.
Highest recovery rates. For decades, WEMCO flotation cells have consistently delivered the highest recovery. WEMCO II's combination of efficient aeration and optimum solids suspension not only increases recovery and concentrate grade performance, but also reduces reagent consumption.
The recent trend of installing flotation cells with volumes as large as 200 m3 in concentrators is driven mainly by economic considerations such as lower capital, operating and maintenance costs. Despite the economic advantages, the metallurgical benefits from these large cells have not yet been fully realised by the industry. This is mainly due to …
Review of researches in control of flotation plants with mechanical flotation cells. • Hierarchy of flotation control levels is often described through 3 or 4 levels. • …
Induced-air flotation cells deliver airflow into the pulp with the turning of the rotor, which pulls in the ambient air. No forced-air supply system is required, eliminating the capital …
The hydrodynamic characteristics of a mechanical flotation cell's transportation zone have a significant impact on its metallurgical performance, especially on coarse particles recovery efficiency.
FL Minerals is the World Leader in Large Cell Technology with the Greatest Installed Capacity of any Flotation Manufacturer FL Dorr-Oliver Eimco pioneered the way for large cell technology. From its first Wemco 257m3 cell installed in 2003, to now even bigger 300m3 cells being installed in Chile. These 26 x 300m3 Wemco cells will
Utilising large-volume flotation cells brings the benefit of lower overall capital expenditure due to lower equipment costs, reduced overall footprint, reduced installation requirements, lower energy consumption, and less units per installation, which leads to far fewer …
