2) Development history
Xiaoyuhe Gold Mine is a small enterprise with a production scale of 25 tons per day in August after the beneficiation test provided by Jilin ** Research Institute, designed by Lanzhou Nonferrous Metallurgical Design and Research Institute, and passed the feasibility study. The plant uses the old plant of the former 812 factory of the Ministry of Electronics Industry, and the beneficiation process adopts the whole mud zinc powder replacement process, with a construction investment of 2.7 million yuan, and was completed and put into operation on May 26, 1993. In 1994, according to the development status of the enterprise, Xiaoyuhe Gold Mine was renamed "Fengxian Xiaoyuhe Gold Mine". In March 1995, in order to achieve large-scale operation, solve the problems of large mud content of raw ore, fine gold inlay particle size, difficulty in solid-liquid separation during dense washing, and metal loss, we invested 1.47 million yuan to "fill in and fill" the concentrator, expanded the beneficiation capacity of 25 tons per day to 50 tons per day, and changed the whole mud zinc cyanide powder replacement process to the whole mud cyanide carbon slurry adsorption gold extraction process.
From 1993 to 1997, Xiaoyuhe Gold Mine relied on self-reliance and hard work to overcome difficulties such as shortage of geological data and insufficient technical strength, and formed a local state-owned enterprise with fixed assets of 5.6 million yuan from small to large.
