Embodiment Construction

[0011] A method for quickly pulverizing and separating tungsten carbide and cobalt carbonate by using waste ultrafine hard alloy bodies, which is characterized in that the method uses waste ultrafine hard alloy bodies as the base material, and is sent to the reaction after crushing, ball milling, and roasting. kettle, add acid solution and catalyst and stir, then press filter and dry to obtain tungsten carbide (WC) powder and cobalt carbonate powder, the specific steps are as follows:

[0012] (1) Material preparation—Using waste ultra-fine cemented carbide body as the base material, analyzing the composition content of the base material with metallographic equipment and Guangpu equipment, sorting and stacking after metallographic analysis;

[0013] (2) Base material pulverization—Using high-frequency impact equipment to crush the cleaned base material into particles, the particle size of which is less than or equal to 10mm, and then sending the base material particles into a h...

Abstract

The present invention provides a method of quick crashing separating and extracting tungsten carbide and cobalt carbonate utilizing waste superfine cemented carbides engine, characterized in that the method adopts waste superfine cemented carbides engine as basic material, tungsten-carbide powder and cobalt carbonate powder are obtained by breaked, ball milled, baked, then feeding in reaction kettle, blending by adding acid liquor and catalyst, then filter pressed and dried, the invention adopts equipment higher-mode vibration break, cementing phase liquefaction separation and pressing filter treatment, not only enhances productivity effect and capacity, but also effectively removes hazardous element and impurity element, the powder is further thining and extracted, and has a high production activity; the prepared cemented carbides obtains evenly distribution crystal grain, hardness and intensity synchronously enhances under the same process, the performance index exceeds native material product.

Description

technical field [0001] The invention relates to a method for quickly pulverizing, separating and extracting tungsten carbide and cobalt carbonate by using a waste ultrafine hard alloy body, which is a method for regeneration, treatment and recovery of waste hard alloy. Background technique [0002] With the increase of tungsten mining and tungsten consumption, the storage of tungsten is becoming increasingly depleted. The use of tungsten as a strategic material is of great significance to the development of the national economy and the full and effective use of resources. High-quality alloys are regarded as a valuable second resource, and they are used as an important means to solve the problem of resource poverty and reduce the cost of alloys. At present, the common recycling methods of waste cemented carbide are: chlorination method, saltpeter melting method, mechanical crushing method, zinc melting method, electrolytic melting method, etc.; Due to the shortcomings of hig...
