Smelting copper slag accretion agent and preparing method thereof

Abstract

A smelting copper slag accretion agent is characterized by comprising, by mass, 74%-78% of perlite, 5%-12.0% of pyrophyllite, 3%-5% of calcium aluminate, 10%-14% of albite and 5%-15% of kaliophilite. A preparing method comprises the steps that firstly, weighing and mixing are carried out, raw materials are weighed according to the formula and weight, and the weighed raw materials are evenly mixed; secondly, crushing is carried out, the mixture obtained in the first step is placed in a crusher to be crushed, and the crushing granularity ranges from 80 meshes to 100 meshes; thirdly, packaging is carried out, powder obtained through crushing is bagged and packaged, and then a finished product is obtained. According to the smelting copper slag accretion agent, the vacancy of the domestic smelting copper industry in the field of the slag accretion field is filled up, the smelting copper slag accretion agent has the advantages of being low in cost, good in slag accretion effect, short in slag drossing time and small in copper loss, and in the using process, toxicity, dust and foreign smell do not exist, and the environment cannot be polluted.

Description

technical field [0001] The invention belongs to the technical field of chemical metallurgy, and relates to a copper smelting slag gathering agent and a preparation method thereof. Background technique [0002] Copper is an alloy that has the smallest shrinkage among non-ferrous alloys. The castings prepared by it are widely used in elastic elements of steam boilers, ships and other machinery and equipment, as well as friction-bearing parts for automobiles and other industries. [0003] During the copper smelting process, since the melting point of some metal oxidation products is lower than the melting temperature of the alloy, these oxides float on the copper water in liquid form, and are not easy to separate from the copper water. If the slag removal is carried out directly, the slag removal time will be too long and the operation will be difficult. At the same time, a large amount of copper water will be lost along with the slag during the slag removal process, resulting...

Problems solved by technology

However, the currently used slag accumulators are mainly imported volcanic ash, the effect is average, and the price is relatively expensive; at the same time, domestic slag accumulator products are relatively rare, which leads to high use and maintenance costs, which limits the domestic copper industry. develop
