Zijin mining group co. LTD

Guizhou zijin mining co., LTD. (subsidiary)

Construction scale: the three phases of the zhenfeng mercury cavern gold mine expansion technical reform project

Construction background: guizhou zijin mining co., LTD., located in zhenfeng county in guizhou province, was founded in December 2001, the registered capital of 200 million yuan, by zijin mining group co., LTD. (56%), guizhou geological mining (27%) and zhenfeng county government common form (10%), is a company specializing in gold exploration and development of enterprises, its core assets for mercury hole gold mine.

The mineral resources base is a gold-mining field with the backslanting of grey houses, with a preliminary investigation of 250.7 tons of resources, and the prospective reserves are expected to exceed 300 tons.

The mercury hole gold mine is underground and adopts the process of "grinding ore - medium temperature chemical preoxidation - carbon dip - cyanide tailings flotation". Construction was started in December 2001. The first gold ingot was released on July 25, 2003, and the second phase was completed in April 2005. Currently, it has the capacity to produce 2 to 3 tons of gold. In 2016, it will produce 1.9 tons of gold, and total profit of RMB 71.75 million. The total assets are now more than 23.43 billion yuan.

In June 2003, guizhou zijin independently developed "heating atmospheric chemical oxidation treatment" gold by wet process, the technology for application of international initiatives in industrial scale production, successfully solved the "card forest" and hard to smelt development the international problem, fill in the our country the microgranular native ore containing carbon arsenic extraction technology of blank, access to the national technology patents, for the development and utilization of the gold mercury hole provides powerful technical support, created a difficult native gold mine in guizhou successful development of precedent. The technology has the advantages of high recycling rate and excellent environmental protection. The project won the first prize of China gold association science and technology.

In order to accelerate the development of low-grade gold resources, the company invested more than 400 million yuan to build 450t/d thermal pressure pre-oxidation technology. The project is the first in the domestic gold industry, not only improving the overall level of local science and technology, but also effectively improving the utilization ratio of metallurgical resources in the vicinity of guizhou province, and improving the core competitiveness of enterprises.
