On March 1, a delegation led by the chairman and technical director of Hunan Taixing Environmental Protection Technology Co., Ltd. came to our company for a pilot test of microwave pretreatment of waste slag. Hunan Taixing Environmental Protection Technology Co., Ltd. is an environmental protection technology enterprise specializing in the treatment of non-ferrous metal arsenic containing waste. Tailings disposal and extraction is a project with strict technology and resource reuse. Microwave technology and process can be used to crack the waste gas and sediment in tailings to obtain many precious metals. Microwave technology and equipment have the characteristics of energy saving, fast temperature rise, good product quality, high energy utilization rate, and no environmental pollution. After many hours of pilot test, the tailings samples were taken out of the furnace, and the tailings became darker from the previous gray, and various metal substances were successfully separated. The customer was very satisfied with the results of the pilot test. After the samples were tested, the process was determined, and then came to our company to negotiate the purchase of microwave technology equipment.
