Sample preparation method for mixed high-copper low-cobalt powdery alloys and high-cobalt low-copper granular alloys

Abstract

The invention discloses a sampling and sample preparation method applied to mixed high-copper low-cobalt powdery alloys and high-cobalt low-copper granular alloys. The used device comprises a shovel, a carry-scraper, a drill bit, a double-roll crusher, a grinder, a 1 / 2 divider and a 1mm sieve. The method comprises the following steps: perform rapid mixing by matching the shovel and the carry-scraper, performing grid sampling by virtue of the drill bit with the special sampling function, screening alloy samples by virtue of the 1mm sieve, and allowing oversize products, namely large particle alloys, to pass through the double-roll crusher and the grinder, so that the alloy granularity is less than 1mm; and uniformly mixing the alloy samples, and rapidly separating the samples by virtue of the divider. According to the method disclosed by the invention, the alloys can be efficiently and rapidly mixed, sampled and prepared, and the prepared sample has the characteristics of high representativeness and high uniformity. Moreover, the operation is easy to operate, the occupied area is small, and the large-scale industrial application is easily realized.

Description

technical field [0001] The invention belongs to the field of metallurgy and analytical chemistry, and in particular relates to a method for directly quickly mixing copper-cobalt red alloys and white alloys with widely different particle sizes and components, and preparing samples. Background technique [0002] my country is a country seriously short of cobalt resources. In recent years, with the rapid development of the economy, especially the rapid development of the lithium battery industry, the demand for cobalt is increasing. In most cases, cobalt is associated with other elements. Copper-cobalt ore is the main source of cobalt. From a global perspective, Africa is especially famous for its copper-cobalt resources in Congo (Kinshasa) and Zambia, and its cobalt reserves are close to the world's cobalt resources. half of the amount. At present, in Africa, especially in the Democratic Republic of the Congo, in addition to the wet process, electric furnace reduction smeltin...
