Zalta™ antiscalants
Mineral processing unavoidably provides many opportunities for insoluble salts to drop out of process water and solutions causing scale to collect on unit operation equipment. This scale consists largely of calcium carbonate and calcium sulfate, but also magnesium and silicate in some instances. These scales will typically deposit out in areas where changes in water conditions such as temperature, pH or agitation occur. Pumps, concentrators, nozzles, filters, gravity circuits, carbon tank screens, strip circuits and drip emitters are all highly prone to scaling. As scale buildup occurs, pipe volume becomes restricted, reducing flow, and ultimately requires downtime for cleaning to restore productivity.
Zalta antiscalants are comprised of a variety of polymer chemistries that control and prevent scale in a wide range of mineral processing applications from process water to Merrill Crowe circuits. These products control scale by preventing initial scale formation (threshold inhibition), preventing hard scale formation by interfering with its structure (crystal modification) or by dispersing scale particles so they cannot adhere to surfaces. Based on the individual application, operating conditions and water chemistry, Ashland will recommend the ideal Zalta antiscalant to maximize your throughput and productivity while minimizing your downtime and product loss.

Zalta antiscalants control and prevent scale formation in a wide range of areas throughout mineral processing operations. Ashland can evaluate the chemistry and conditions in each of these areas and recommend the optimum antiscalant protection for maintaining the best process efficiency. Commercial applications confirm this and typically result in a number of value-added benefits.
● Increased production
● Reduced downtime
● Reduced cleaning costs
● Improved recovery
● Reduced fresh water usage
● Improved capital asset life
● Optimized reagent feed rates
