PURPOSE: A high-purity copper oxide is provided which is produced from etching wasted liquid without intermediate products and has seamless crystal phase. CONSTITUTION: A production process contains the following steps of: (1) a first step wherein a copper chloride wasted liquid is added to a ...
Copper(II) oxide powder manufacture from H2O2 type etching waste is proposed. The basic copper carbonate, the intermediate product, is depends on the react... YKS Lee - 《Journal of Industrial & Engineering Chemistry》 被引量: 0发表: 2019年 Innovative environmentally friendly technology for copper...
PROCESSING OF OXIDE ORE : Oxide ores are generally processed using hydrometallurgy. Liquid solutions are used in these processes to extract and purify copper from copper oxide ores at ordinary temperatures, in three major steps: 1) heap leaching -to leach out metals, 2) solvent extraction- to s...
Production of zinc oxide from complex sulfide concentrates using chloride processing The present invention relates to an apparatus and a process for producing zinc oxide from a zinc-bearing material. The process according to the present invention comprises the steps of leaching the complex sulfide mater...
changes. Consequently, it is ductile and possesses a high level of electrical andthermal conductivity, making it attractive for a wide range of ornamental and practical applications. With cold-working, copper becomes harder, but it can be made soft again with the heat treating process known as ...
Photoelectrochemical water splitting is a promising solution for harnessing solar radiation for hydrogen production. Copper oxide semiconductors, particularly materials based on cuprous oxide, have attracted attention due to their abundant elemental availability and scalable synthesis methods. To improve the gen...
