About us

Linyi Xinmailong Building Materials Co., Ltd. is located in feixian County, Linyi City, Shandong Province. The company is committed to the development of wet smelting technology and supporting equipment for non-ferrous metals such as copper. It is one of the first companies in China to invent, produce, and manufacture microbubble neutralization tank copper dissolution devices.

 The current production of microbubble neutralization tank copper dissolution devices has achieved the goal of high-speed self heating copper dissolution using air as an oxidant at room temperature and pressure, while solving the problems of wet leaching of copper, tin, nickel, cobalt and other alloys, as well as wet separation of other alloys;

 The crystallization machine developed, produced, and manufactured by our company has achieved low energy consumption and high efficiency crystallization of copper sulfate;

 The sponge copper replacement machine can replace sponge copper with a grade of 95% or higher.

Our company has independent workshop buildings, professional personnel, and senior engineering and technical personnel cooperation, with strong technical research and development capabilities, and can undertake technical problem solving tasks proposed by users.

 Main products: microbubble neutralization tank (copper dissolution kettle - leaching copper, tin, nickel, cobalt metals and their alloys), copper sulfate crystallizer, sponge copper replacement machine, settler, simple submersible pump, etc.

Technical services: We can provide design, non-standard matching, and technical services for copper sulfate pentahydrate production lines and other special raw material separation and extraction production lines.
