Recently, the invention "A PROCESS FOR INITIATION OF COPPER SULFIDE HEAP BIOLEACHING USING WATER IRRIGATION" jointly applied by Wanbao Minerals Co., Ltd. (hereinafter referred to as "the company") and the Institute of Processes of the Chinese Academy of Sciences Obtained the PCT (Patent Cooperation Agreement) patent authorization in Australia. This patent is the company's first international invention patent authorized since the intellectual property protection work was carried out in 2014, marking the company's intellectual property protection work is gradually in line with international standards, and in key technologies The field is recognized by the International Patent Organization.
The patent relies on the company's Myanmar project copper sulfide mine biological heap leaching process, by using clean water spray instead of sulfuric acid spray to start the acid cycle of the mine heap solution system to achieve the solution ferric acid concentration and use Acidthiobacillus (thiobacillus) and Leptospirillum (hook end Spirulina) The construction of high-efficiency ore-leaching microbial population. This technology was successfully applied to the company's Myanmar Lebitong Copper Mine Project from 2015 to 2016, which not only played a key role in the rapid start-up and commissioning of the project, but also effectively relieved the excess acid pressure caused by the late pyrite oxidation and acid production. In view of the new concept of green production in mines, the successful application of this technology has realized a total economic benefit of 8.11 million US dollars.
