Solids removal mining industry before RO in Africa

Gold Field Industry 

Polluted with TSS

The goldfields in Africa is one of the largest gold producers in the world. However, the leaching water produced during mining is polluted with TSS. We developed the following system to remove the pollution from their water: a flocculation system with poly-electrolyte treatment followed by a settling tank. Our specialists took control of the whole project, from design to realisation. The purification installation was handed over in March 2013.
Removal of TSS
TSS is a coarse pollutant. It is treated by, for example, using bow screens and rotating drum filters. Flotation is used to separate fats, oils and solid particles smaller than 1 mm from the water. However, in many cases, coagulants, flocculants and neutralisers are needed to achieve high yields. Pollutants can be flocculated using a flocculator: this is a tubular reactor where chemicals for coagulation, flocculation and neutralisation are added to waste water under controlled circumstances.

The gold fields in Africa is one of the largest producers of gold in the world.  The leach wastewater, with an input of 300-380 m3/h,  coming from the mining operation is polluted with TSS.

Colubris Cleantech

Profitable Solution

In order to remove the TSS we delivered a flocculation system with poly electrolyte treatment, followed by a cross flow separator to be placed before the RO. The separator removes settling as well as floating materials. Furthermore it is a compact- and custom built installation.
