About Yantai Kaishi Industrial Co., Ltd.'s annual output of 10,000 tons of electrowinning cobalt technology transformation project

Environmental impact report (draft for comments) is larger than the public announcement

1. Project Overview

(1) Project name: Technical transformation project of electrowinning cobalt with an annual output of 10,000 tons

(2) Project location: No. 215, Xingfu Middle Road, Zhifu District, Yantai City

(3) Construction content and scale: Yantai Kaishi Industrial Co., Ltd. was established in 2002. It is a large and medium-sized enterprise mainly engaged in cobalt metal hydrometallurgy and integrating scientific research and development, production and operation, and comprehensive utilization of resources. The company's current main products For the electrowinning of cobalt, due to the problem of raw material supply, the raw material was changed from water cobalt ore to nickel cobalt hydroxide, and the metal composition and grade of the raw material changed greatly, from cobalt metal to nickel metal, and nickel metal in the raw material. The increase in the content leads to an increase in the pressure of the electrolytic nickel section, the production capacity of the electrolytic nickel workshop can no longer meet the production needs, and the existing reserve raw materials and the nickel solution in the purification system cannot be put into the electrolytic nickel system in time, which affects the system efficiency. In order to ensure the balance of the production system, the formation of High-efficiency production closed-circuit circulation system, the company plans to carry out technical transformation of the existing nickel electrowinning section, using the more advanced leaching, extraction technology, high-efficiency evaporation technology, sulfuric acid system electrowinning technology, from nickel-cobalt hydroxide in the industry. Recover nickel and cobalt metals, and carry out deep processing to produce electrowinning cobalt and battery-grade nickel sulfate. The process route is short, and the whole process is closed. After the transformation, on the basis of the existing production equipment, the annual production of electrowinning cobalt can reach 10,000 tons. , battery grade nickel sulfate 50000 tons.
