Solutions for recovering metals

by Calgon Carbon Corporation     based in Pittsburgh, PENNSYLVANIA (USA)

The mining industry relies on Calgon Carbon’s Granular Activated Carbon (GAC) to recover gold and other precious metals. Calgon Carbon’s ISEP® Technology is used to recover precious, rare earth and base metals, uranium, copper, nickel and zinc from ore, waste and reclaim streams. Our high-quality activated carbons have been developed and successfully proven to maximize efficiency by reducing the loss of precious metals and the consumption of carbon in three precious metal extraction techniques: Carbon-in-Leach (CIL), Carbon-in-Pulp (CIP) and Carbon-in-Column (CIC). When Ion Exchange is employed for metal recovery in leach and waste streams, Calgon Carbon’s ISEP ® system provides a continuous, consistent and high purity concentrated product while minimizing the use of chemicals, resin and wastes. Calgon Carbon’s continuous ion exchange systems are the most flexible, robust, and accepted in the industry.

Industrial water demineralisation

by PuriTech Ltd     based in Herentals, BELGIUM

Deionized water, also known as demineralised water, is water that has had its mineral ions removed, such as cations like sodium, potassium, calcium, magnesium, iron, and anions such as chloride, nitrate, sulfate, bicarbonate and even silica. Deionization is a chemical process that uses specially manufactured ion exchange resins which exchange hydrogen ion and hydroxide ion for dissolved minerals, which then recombine to form water. Because the majority of water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, and this process is quick and without scale buildup.

Industrial water Gold and Silver

by PuriTech Ltd     based in Herentals, BELGIUM

Cyanidation is still the most widely used method to leach gold, using sodium or calcium cyanide as lixiviant. An anionic gold-cyanide complex is formed that is extractable by basic resins. Other metals present in the ore, such as silver and base metals ( copper, nickel, cobalt, zinc, iron, etc. ) are also leached in cyanide media. Selective ion exchange resins are designed to preferentially adsorb the mono-valent gold-cyanide species.

Removal of impurities for food and beverage industry

by Calgon Carbon Corporation     based in Pittsburgh, PENNSYLVANIA (USA)

As a world leader in purification, separation, and concentration technologies, Calgon Carbon offers one of the largest selections of products and services in the food and beverage industry. By removing impurities such as color and odor from food liquids, syrups (e.g. sucrose, dextrose, glucose), organic acids, amino acids, vitamins, beverage alcohols, and glycerin, our products are vital to the production of high-quality, stable products.

Advanced water treatment equipments for deionization

by Advanced Equipment and Services, Inc. (AESINC)     based in Coconut Creek, FLORIDA (USA)

Deionized water, also known as demineralized water (DI water or de-ionized water; can also be spelled deionised water), is water that has had its mineral ions removed, such as cations from sodium, calcium, iron, copper and anions such as chloride and bromide. Deionization is a physical process which uses specially-manufactured ion exchange resins which bind to and filter out the mineral salts from water. Because the majority of water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, and this process is quick and without scale buildup. However, deionization does not significantly remove uncharged organic molecules, viruses or bacteria, except by incidental trapping in the resin. Specially made strong base anion resins can remove Gram-negative bacteria. Deionization can be done continuously and inexpensively using electrodeionization.

Deionized Water Testing

by Myron L Company     based in Carlsbad, CALIFORNIA (USA)

Years ago, high purity water was used only in limited applications. Today, deionized (Dl) water has become an essential ingredient in hundreds of applications including: medical, laboratory, pharmaceutical, cosmetics, electronics manufacturing, food processing, plating, countless industrial processes, and even the final rinse at the local car wash.

Trislot screens for the pharmaceutical industry

by Trislot N.V.     based in Waregem, BELGIUM

Trislot screens have many applications also in the pharmaceutical industry. Besides the classical application in water treatment systems (ion exchange, molecular sieve,... ) the screen are used for classification and in dryers/coolers. The Sintered Laminate is used in Nutsche filters for the pharmaceutical industry.

Ultra pure water treatment

by Lenntech Water Treatment     based in Delft, NETHERLANDS

Ultra pure water is mainly used in the semi conductor and pharmaceutical industry. Because of the continuing miniaturilisation in the semi conductor industry, the specifications become more strict every year. Ultra-pure water contains by definition only H20, and H+ and OH- ions in equilibrium. Therefore, ultrapure water conductivity is about 0,054 uS/cm at 25oC, also expressed as resistivity of 18,3 MOhm.

Advanced water treatment equipments for ion exchange

by Advanced Equipment and Services, Inc. (AESINC)     based in Coconut Creek, FLORIDA (USA)

Ion exchange is an exchange of ions between two electrolytes or between an electrolyte solution and a complex. In most cases the term is used to denote the processes of purification, separation, and decontamination of aqueous and other ion-containing solutions with solid polymeric or mineralic `ion exchangers`.
