A line of subtitle text I trade metals and electroplating products The Co.met headquarters is one more large and modern structure in which collaborators and owners boast years of work experience in this sector. © Made by VirtualSpace 360 Our trusted references Nickel The bulk of all nickel is extracted from two types of mineral deposits; the first type are laterites in which the main mineral are nickeliferous limonite [(Fe, Ni) O (OH)] and garnierite (a hydrated silicate of nickel). The second type are sulfide deposits of magmatic origin in which the main mineral is pentlandite [(Ni, Fe) 9S8]. Nickel is also found in kamacite, a natural alloy of iron and nickel. The largest reserves of nickel are in Australia and New Caledonia and amount to approximately 45% of the total known reserves. However, it is estimated that, starting from the emerged areas in which at least 1% of concentration of nickel, the available nickel resources are at least 130 million tons (about double the already known reserves). 60% are in laterites and 40% in sulphide deposits. In 2011, Russia was the largest nickel producer with around 20% of the world production closely followed by Canada, Australia, Indonesia and the Philippines. Copper Primary copper is the copper content extracted from mines, which can be refined on site or shipped to refineries in the form of concentrates. Refined copper is instead the product of refining, generally electrolytic, not only that primary from the mine, but also of that obtained from the recycling of scrap. It is estimated that on average 17% of refined production comes from scrap. Notice that a considerable part of the scrap copper and its alloys is used directly in the foundry, without the need to go through refining cycles. Double Cyanide Gold Potassium cyanide, and cyanide ion in general, is very important in chemistry because it is capable of creating soluble complexes with many metals (gold, iron, silver, nickel) and is then exploited in the analysis techniques to solubilize the various cations metallic, such as for the cyaniding of steel. It is also used in photography for i fixing baths, to remove silver halides. In organic chemistry it is a typical synthesis reagent that can be added by nucleophilic substitutions, lengthening the carbon chain. For its great ability to complex metals transition, is used for the preparation of potassium and sodium salts. Between these those of gold and silver stand out: KAu (CN) 2, KAu (CN) 4, KAg (CN) 2. These are used in electroplating for plating (gilding or silvering), both jewelry and electronic components.
