SMM News: recently, eight technicians from the Zinc Plant in Rajasthan, India, completed on-site technical training in Yunnan Chihong Zinc and Germanium Co., Ltd., which means that the technology of Chihong Zinc and Germanium with independent intellectual property rights will go out of the country for the first time. Created benefits. According to the contract signed between the two sides, the electric slag plug device of Chihong zinc and germanium has been shipped to the Zinc Plant in Rajasthan, India, the fumigation furnace operation manual has been provided to the Indian side, and the contents of the contract have been fulfilled more than half.
Prior to the construction of the "valuable Metal recovery Project for Zinc Slag treatment in India", the Zinc Slag treatment Technology in Rajasthan, India, was investigated in many countries before the construction of the "valuable Metal recovery Project for Zinc Slag treatment in India". The technology of zinc germanium fumigation furnace in China, which has great advantages, stands out. After that, Through the project contractor, China Nonferrous Metals Construction Co., Ltd., the Zinc Plant in Rajasthan, India, negotiated with Chihong Zinc and Germanium and signed the "contract for the supply of equipment for the Zinc Slag treatment Project in India" (Electric Slag plug device) and "Zinc Slag treatment". Valuable metal recovery project fuming furnace training and start-up technical service contract ", A total of 9.547 million yuan (excluding labor fees) need to be paid to Chihong zinc and germanium technical service fees and equipment fees.
