Flotation Separators Overflow Velocity Requirements

Hongxing's flotation separators are designed to provide the most effective pool area and overflow velocity requirements. By combining the proper submergence of the spiral with one of the tank designs a choice of 63 combinations is possible in Straight, Modified or Full flare tank designs.

The Purestream vertical IGF process is a proven technology that has been widely used in onshore and offshore gas and oil exploration since the 1970’s. It is a valuable component that provides real solutions in waste water management as both a stand-alone application or an integral component in waste water management plants. Purestream has improved upon this technology and developed an enclosed IGF skid capable of processing 2500 bbl/day of input stream.

The sludge from the smelting plant and the converters formed as a result of the smelting process are processed in a flotation plant in order to extract the remaining copper.

The proper combination of pool depth, area and spiral construction is important to secure a controlled turbulence in the slurry flow for accurate size separation. The flotation method of enrichment is used, where two products are obtained: copper concentrate, which is returned back to the smelting production process; fayalite (iron sand), part of which is stored in a depot in a tailing dam built according to the latest European standards.

Waste water containing fat and protein is precipitated in the flotation unit in the form of flotation sludge which floats towards the top. A skimmer then removes the floating sludge off the surface of the water. The next process stage heats it to around 90 °C. This coagulates the proteins and the fat is released. A 3-phase decanter can now separate the sludge into its fat, solids and water components. The water phase can be used for preheating the product, for the pre-heating stage and on to flotation on the countercurrent principle. The technological process is controlled and managed with an automatic system....
