Highest quality standards are achieved through the implementations of latest technology, decades of experience and everlasting moral values , which have helped us to retain our customers as well as multiply them.
We import and export high quality of Zinc Cyanide – zn-54%. It is a inorganic chemical compound with the formula Zn(CN)2. It is free from impurities and safe to use. It is fabricated using high quality material in accordance with the international quality standard. It finds application in diverse industry and can be availed as per the specific requirement of the clients.
It adopts a polymeric structure consisting of tetrahedral zinc centers linked by bridging cyanide ligands. The structure can also be described as being two interpenetrating adamantine structures. The cyanide group shows head to tail disorder with any zinc atom having between 1 and 4 carbon neighbors and the remaining being nitrogen atoms. It shows one of the largest negative coefficients of thermal expansion, beating the previous largest zirconium tungstate.
Zinc Cyanide complex was found to be particularly acceptable due to it is preferred by the strong base resin groups to gold and silver complexes, it is readily decomposed by a mildly acidic solution so that zinc and cyanide ions removed while the resin is regenerated for further use, and zinc is a metal which is compatible with most cyanide circuits using the Merrill-Crowe technology. One of the first methods employed a zinc cyanide solution which is passed through a resin bed. The rich solution obtained can be sent to a Merrill-Crowe process or electrowinning, and the zinc cyanide solution can be recycled to elution. In this method all the anionic cyanide complexes are eluted efficiently and the resin can be regenerated to full capacity each cycle with efficient recycle of chemicals.
