Nalco has released a brochure entitled 'POL-E-Z® Liquid Flocculants Water Clarification Made Easy' on Mining...
One of the key elements needed to successfully run a coal preparation plant is properly managing water supplies and maximising water recycle and limiting carbonaceous solids disposal. Most operations use thickeners followed by either twin belt press filters or pond/dewatering cells.
Flocculants and coagulants are typically required to remove solids and produce required settling rates to permit clean recycle water that is needed for the continuous cleaning of fine coal. These products are also used to optimise the underflow density in the thickener and percent cake solids on dewatering filters.
Flocculants are key to any water management regimen and are available in liquid or powder form. While powders can appear to be less expensive, their use can often involve significant additional and largely hidden costs and hazards. Liquids can help the environmentally responsible operator avoid these issues.
