HiraChem is your specialist supplier of Granular Activated Carbon.
Pure carbon which is gold recovery granular activated carbon is coconut-shell-based granular activated carbons specially designed for gold recovery operations. GR was developed to be a consistent, high performance, high activity gold recovery carbon product line. The activated carbon's ability to achieve high gold loadings and the relative ease with which they can be stripped enables gold processors to obtain the highest possible yields from ores with high silver/gold ratios, carbonaceous ores and ores containing other metals that complex with cyanide; for example, copper and nickel. In Carbon in Leach (CIL), Carbon in Pulp (CIP), and Carbon in Column (CIC) circuits, it is essential that the activated carbon employed provides excellent process performance, minimal losses due to attrition, and minimal maintenance problems.
Through the years, Pure carbon has continually upgraded its manufacturing processes to ensure that it continues to provide high quality products. Steps have been added to the manufacturing process which have improved the carbon's resistance to abrasion and reduced its tendency to plug retention screens in adsorption tanks. Platelets (flatter granules which are relatively long and wide while not particularly thick) can end up oriented in such a manner that they pass through the retention screens. This results in a loss of gold-containing carbon, which directly affects percent recovery and pro stability. In order to have a product that has less tendency to plug screens with "platelets," GR is also processed through a vee-wire screen and deÃ?Âdusted. GR products are manufactured specifically for gold adsorption. As a result, the quality of the carbon is extremely consistent and tailored to gold recovery applications. GR activated carbon enable the extraction of even trace amounts of gold from every ton of ore, even when processing average or low-grade ores. Pure Carbon expertise in activated carbon application technology is a valuable resource for designing and optimizing.

HiraChem is your specialist supplier of Silver Mercury.
Mercury (also known as quicksilver) is the only metal which is liquid at room temperature - it is well known for it's use in thermometers, but it is also widely used in scientific research, for dental restoration and in lighting.
Mercury forms alloys with different metals easily - these alloys (called amalgams) can be used for creating dental fillings and are in use to create long-life batteries.
IT'S MAIN APPLICATIONS ARE:
AS CATALYST FOR THE PRODUCTION OF PVC (POLYVINYL CHLORIDE)
IN ENERGY EFFICIENT CFL (COMPACT FLUORESCENT LIGHT) BULBS
IN CATHODE CELLS
IN INDUSTRIAL CHEMICALS
IN PAINTS
HiraChem is your specialist supplier of Sodium Hydroxide.
Sodium Hydroxide (Caustic Soda ) 98-99% Flakes.
Sodium Hydroxide, also known as lye and caustic soda, is an inorganic compound with formula NaOH. It is a white solid, a salt (ionic compound), consisting of sodium cations Na+ and hydroxide anions OHâ??. Sodium hydroxide is a highly caustic base and alkali, that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. It is highly soluble in water and readily absorbs moisture and carbon dioxide from the air. It forms a series of hydrates NaOH·nH2O. The monohydrate NaOH·H2O cystallizes from water solutions between 12.3 and 61.8 C. The commercially available "sodium hydroxide" is often this monohydrate, and published data may refer to it instead of the anhydrous compound
