Antiscalant an overview ScienceDirect Topics

Antiscalants are a family of chemicals designed to inhibit the formation and precipitation of crystallized mineral salts that form scale. Most antiscalants are proprietary organic man-made polymers (e.g., polyacrylic acids, carboxylic acids, polymaleic acids, organophosphates, polyphosphates, phosphonates, anionic polymers, etc.).

Antiscalants for Calcium Scale Control in Gold Process

Jan 01, 2014· "Antiscalants were evaluated for control of calcium carbonate (CaCO3) in gold processing applications. Under severely supersaturated conditions, 100 percent inhibition was achieved with 30 ppm antiscalant. Laboratory and field testing established that an antiscalant could both inhibit scale buildup and remove an estimated 0.5 kg/m2 per annum of

An overview of the use of chemical reagents in mineral

Feb 01, 2005· 5.4. Antiscalants. In many operations that use lime, calcium carbonate or calcite scaling can be a major problem. For example, in gold processing, restriction in pipe flow, screen scaling and precipitation in activated carbon pores lead to processing inefficiencies. Also, in heap leaching operations, blockage of sprinklers can occur.

Scaling and antiscalants Lenntech

Scaling phenomenon, control and prevention. Scaling means the deposition of particles on a membrane, causing it to plug. Without some means of scale inhibition, reverse osmosis (RO) membranes and flow passages within membrane elements will scale due to precipitation of sparingly soluble gas, such as calcium carbonate, calcium sulfate, barium sulfate and strontium sulfate.

Mineral processing metallurgy Britannica

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.The primary operations are comminution and concentration, but there are other important operations

Testing the Performance of Various Polymeric Antiscalants

Scaling is frequently observed in geothermal fields and reduces the energy harvesting of power plants. Recently, Sb-rich deposits have developed in many fields around the world. Various polymeric macromolecules have been used as antiscalants to mitigate the formation of scale. Testing potential commercial antiscalants in field conditions is a tedious and costly process.

Dispersants & Antiscalants for Water Treatment Brenntag

MINING AND SLURRY TREATMENT. When mining, the extraction of calcium, phosphate, kaolin, and sand often requires the minerals to be mixed with water to form a slurry.. A slurry is a mixture of a solid and liquid which has a natural tendency to separate. If separation does occur several transportation, storage, and manufacturing problems can arise, including difficulty pumping or problems with
