Metal and Mineral Processing
The mining and mineral processing industries utilize large quantities of water to separate and recover valuable minerals.  Many of these processes have a number of stages where polyelectrolytes assist in the separation of solid particles from aqueous suspensions.
 
Some application areas are :
Alumina  
-
red mud treatment.
Zinc  
-
acid leach process, silver flotation/filtration.
Titanium dioxide
-
black liquor leach process, hydrate filtration.
Iron ore  
-
tailings clarification, pelletisation.
 
There are several applications where it is necessary to clarify process water to recover valuable minerals or to consolidate unwanted tailings.
 
Clarification of raw water.
Recovery of water from tailings.
Clarification of effluents.
Clarification of underground water.
Clarification of process leach liquors.
 
A number of mechanical dewatering systems are used in the mining industry to concentrate recovered products or wastes into a manageable form.  These include vacuum filtration, pressure filtration and centrifugation.  Polyelectrolytes are used to impart a strong porous structure to the filter cake which results in higher throughputs, drier cakes and cleaner filtrates.
 
Effluent  Treatment
Contaminated industrial effluents and municipal sewage are treated in purification plants to remove both suspended and dissolved contaminants. A major part of processing effluents and sewage is the removal of suspended solids through sedimentation and the consolidation of recovered sludge using mechanical dewatering systems.  The extensive range of polyelectrolytes greatly enhance the efficiency of these processes resulting in higher throughputs and improved quality.  Inorganic coagulated effluents produce bulky precipitates causing disposal problems, the use of polyelectrolytes helps to consolidate the sludge, permitting as much as 60 to 70% of the water to be recycled.  Effluents conditioned in this way respond well to the drying bed filtration process.

Paper Manufacture
The paper and board industry produce many different products from a variety of stock furnishes to meet the ever increasing demands of the printer and the consumer.  The variety of furnishes has made suppliers of retention and drainage products expand and improve their range to meet the industry’s requirement in respect of fiber/filler retention and water removal.  We offer  a range of polymers which act as:

 
Retention aids: Use of these chemicals improves paper quality by improving paper formation, reducing delamination, reducing white water solids and increasing machine speed.
Dry strength resins: Synthetic dry strength agents improve fibre to fiber bonding in a wide range of paper and boards.
Polymeric dispersants: For effective dispersion of the pigments currently used in paper coating drainage aids and for improving the removal of water from the drainage section.
Potable Water treatment :
Generally water has to be purified through a treatment plant before it is distributed for consumption to the public.  Treatment plants are designed to kill bacteria and remove particulate matter, colour and certain soluble ions and ensure that the resultant water quality conforms to world standards.  Chlorine is mainly used to kill bacteria.  The suspended solids and color are removed through a clarification process involving precipitation with inorganic coagulants, followed by flocculation  with a suitable high molecular weight polyacrylamide from the range of polyelectrolytes.  Alum is not totally used in the coagulation process and the unused portion forms a hydroxide precipitate which causes co-precipitation of suspended solids.  The use of polyelectrolytes considerably reduces the alum by flocculation of the suspended matter.  This also has the added benefit of reducing the final sludge volume by increased compaction hence improving disposal.
 
Sugar Juice Clarification :
High molecular weight polyelectrolytes of approved quality are used in sugar juice clarification.  The sugar mills benefit from these products in the following ways:
 
Improved clarification
Increased throughput
Lower retention time
Lower heat loss
Reduced sugar inversion
Reduced lime addition
 
All leading to improved sugar recovery.

Coal Washeries :
New mining techniques result in fine coal particles.  Flocculants have been used increasingly for recovering coal from tailings as a settling aid or by filtration/centrifugation by dewatering methods.  In addition to controlling pollution, the large quantities of water used in washeries can be recycled using polyelectrolytes.

Brine Clarification :
Polyelectrolytes have been developed to replace the natural flocculants once used to improve the efficiency of solids removal in the brine circuit.  These specific grades are designed to have very low levels to metal contaminants, especially mercury.

Oil Field Services :
High performance polymers are used in all areas of the industry – production drilling, core drilling, water shut off, mobility control, fracturing, workovers, completions,  solids removal, shale inhibition, produced fluid treatment and in certain EOR (Enhanced Oil Recovery) techniques such as polymer flooding.
