Nowadays, with attention paid to the global environmental problems, climate change, energy and low-carbon economy has been the major concern of the international community. A personage inside course of study points out, energy-saving and environmental protection mining machinery will be the medicine to response to the market risk.
Slag is a partially vitreous by-product of smelting ore to separate the metal fraction from the unwanted fraction. It can usually be considered to be a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides (see also matte) and metal atoms in the elemental form. While slags are generally used as a waste removal mechanism in metal smelting, they can also serve other purposes, such as assisting in the temperature control of the smelting; and also minimizing any re-oxidation of the final liquid metal product before the molten metal is removed from the furnace and used to make solid metal.
Although it is difficult to realize the recycling and comprehensive utilization of slag resource in the mining, smelting, manufacturing and other industrial sectors, the foreign large enterprises have created a variety of recycling and comprehensive utilization forms and methods. There are:
First, various forms of recycling resources, including: recovery and recycling, mutually beneficial cycle, feedback loops, decomposition cycle, etc.
Second, various methods to improve the comprehensive utilization rate, including: a variety use of a resource at the same time; continuously utilization the emissions produced by various resources; combination of utilization process of related resources.
Third, comprehensive development and utilization of renewable energy;
In the above several proposes, the jaw crusher can play a huge role to promote the further use of slag resource.
