Established on September 27, 2002, Lingbao Gold Co., Ltd. is mainly engaged in the exploration, mining, smelting, refining, and deep processing and sales of copper products and its associated elements. Its main products are gold, silver, electrolytic copper, copper foil and sulfuric acid. Now it owns gold smelting, two branches in Nanshan and 26 subsidiaries. In May 2017, it was renamed Lingbao Gold Group Co., Ltd.
Lingbao Lingxin Gold Smelting Co., Ltd. (originally founded in 1989, has been called Huaxin Smelter, Lingbao Gold Smelter, this report is referred to as "Lingxin Smelter") is Lingbao Gold Group Co., Ltd. The company's core enterprise, legal representative Yuan Kezhen, is located in Daonan Industrial Zone, Lingbao City, covering an area of 360 acres and has 400 million yuan in fixed assets. The main business is smelting, refining and further processing of copper products. The company uses gold concentrate as the main production raw material, adopts advanced gold concentrate slurry feed, boiling furnace acidification roasting, SO 2 flue gas to make acid, acid leaching copper, extraction-electrolysis to produce electrolytic copper, cyanide leaching, zinc Process technology for extracting gold and silver by powder replacement and refining cast gold ingot by electrolytic method. From the last round of clean production to the current round of clean production review, Lingxin Smeltery has a total of five branches, namely the first branch, the second branch, the third branch, the water treatment branch and the refinery branch. One of the two plants has two sets of boiling furnace roasting and acid-making systems (each set of gold concentrate 50t / d (100t / d in total)), two cyanide leaching sections and two zinc powder replacement sections; the second branch has two sets of boiling furnaces Roasting acid production system (one set of 200t / d for processing gold concentrates and 150t / d for one set of gold concentrates), one acid leaching extraction and electrodeposition copper section, cyanide leaching section and zinc powder replacement section; one in the third branch plant Set of boiling furnace roasting acid system (treatment of 150t / d gold concentrate), a cyanide leaching section and zinc powder replacement section; the water treatment branch contains acid leaching solution for copper extraction and sewage treatment; the refining branch is responsible for gold slime refining. The production scale is 260,000 tons of gold concentrate processed annually, and it is one of the large-scale gold smelting enterprises in the country. The products include "Lingjin" brand national standard No. 2 gold ingots, silver, electrolytic copper, sulfuric acid, etc. The annual production scale is about 14 tons of gold, 40 tons of silver, 13,000 tons of electrolytic copper, and 150,000 tons of sulfuric acid.
The main energy types and consumption in the production process are shown in Table 1.
