Linjia Sandaogou Gold Mine was founded in August 2010, with its construction inOctober, starting production as of March 30, 2013. Currently, the mine has 350 employees and operates at an annual production capacity of 210,000 tons of fine gold ores. Exploring and summarizing a mining method for the ore bodies that are “steep, narrow, thin, and discontinuous”, it relentlessly refines the review concerning “ore body defining, mining scope control, blast-hole pattern, and roof support” to improve the milling grade and recovery rate; It has also overcome the difficulty in arsenic-bearing ore dressing while it keeps improving its processes for ore grinding, sieving, and flotation. It is industry-leading in ore-dressing processes and successfully keeps its recovery rate at a higher level.
