The Unjong Taehung Scientific Research Institute developed a precious metal leaching agent using locally available raw materials.

According to Choe Jong Chol, section chief and key developer, the new leaching agent is six times better than imported one in terms of environmental index and over 5 percent greater in leaching yield.

It also costs 20 percent less.

The agent is odourless and convenient to store and transport and there is no hydrolysis during the use.

The agent received national standard twice and was registered as a national patent last year. And the detoxification additive used in making the agent was listed as a national high-tech product last year.

This product has been introduced in several local mines to win users’ favour.
