Embodiment Construction

[0013] In order to make the purpose, content, and advantages of the present invention clearer, the specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0014] The invention provides a method for rapid mixing and sample preparation of high-copper and low-cobalt powdery red alloys with large differences in particle and composition and high-cobalt and low-copper granular white alloys. Crusher, grinder, reducer, 1mm sieve; specifically include the following steps:

[0015] Step 1, mixing red alloys and white alloys with different particle sizes and different copper and cobalt contents, basically maintaining the order of one red alloy and one white alloy during operation, and premixing;

[0016] In step 2, the pre-mixed red and white alloys are shoveled and mixed for 3-5 times by the scraper, and the final alloy pile is in the shape of a triangular prism;

[0017] Step 3: Scribe the f...

Abstract

The invention discloses a sampling and sample preparation method suitable for mixing powdery red alloy with high copper and low cobalt and granular white alloy with high cobalt and low copper. Machine, 1 / 2 shrinking device, 1 mm sieve, use shovel and scraper to quickly mix samples, use cuttings with special sampling function to carry out grid sampling, alloy samples are sieved by 1 mm sieve, and the material on the sieve is large The granular alloy is passed through a double-roller crusher and a grinder to make the alloy particle size less than 1mm, and then the alloy sample is mixed and quickly separated by a shrinker. The invention can efficiently realize the rapid mixing, sampling and sample preparation of the alloy, and the sample has the characteristics of strong representativeness and good uniformity after the sample is made, and the method is simple to operate, occupies a small area, and is easy for large-scale industrial application.

Description

technical field [0001] The invention belongs to the fields of metallurgy and analytical chemistry, and in particular relates to a method for rapidly mixing and preparing samples of copper-cobalt red alloys and white alloys with greatly different particle sizes and compositions. Background technique [0002] my country is a country with a serious shortage of cobalt resources. In recent years, with the rapid economic development, 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, the smelting process of copper-cobalt ore is not only the wet proce...
