Integrated procedure for recycling and valorization of useful components from secondary raw materials based on hard metals

Abstract

Wide application of hard metals requires increased consumption of their constituents. Their high cost and scarcity impose the need for finding new, both ecologically and economically justified ways for their production. In presented research, on the basis of previous research, a review of an integrated technological procedure of recycling and valorization of useful components from hard metals secondary raw materials is given.Integrated procedure for processing of hard metal's waste enables the preparation of a wide range of powders with required properties, a high efficiency and reducing the duration of individual stages of procedures for their processing. Therefore, besides conservation of natural resources there are also significant economic and energetic benefits. The developed technological procedure is in service of sustainable development.

Chemical durability of sintered glass-composite prepared from glass cullet and waste foundry sand

“…This process reduces the need for natural raw materials, saves energy in production, and reduces environmental pollution. Numerous studies have reported that the waste from different industrial processes can be utilized successfully in the fabrication of new valuable materials [1][2][3][4][5][6][7].…”
