Method for fast crushing separating extracting tungsten carbide and cobalt carbonate by using waste ultra-fine hard alloy body

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...

Problems solved by technology

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 high energy consumption, or environmental pollution, long process flow, or high impurity content, the performance of the produced cemented carbide products cannot meet the requirements, so the above methods have not been widely popularized and promoted.
