resources which are landfilled as waste materials into useful products, and reach an absolute recycling. The metallurgical industry is directing their efforts into minimizing and processing the slags in order to meet their environmental responsibility. Various metallurgical slags are generated in metal extraction, refining and alloying processes.
01/03/2007#0183;#32;Significant quantities of sludge and slag are generated as waste material or byproduct every day from steel industries. They usually contain considerable quantities of valuable metals and materials. It is generally possible to recover some values by physical or chemical mineral processing techniques such as crushing, grinding, classification, hydrocyclone, magnetic separation, flotation, leaching or roasting.

In natural stone processing, an excavator transfers pieces of feed material, the rock to be processed, to the mobile crusher. When processing recycled material, construction waste, concrete, asphalt, or waste incineration and steel mill slags are processed as aggregates for road construction and other applications.
We work with licensed companies for the handling and transport of these materials from our customers works and to our partners processing facilities. Independent Analysis and Verification: Earth Metals arranges for independent weighing and analysis by independent and internationally recognized assayers, for example: RC Inspection, Knight, and Alex Stewart Assayers.
30/05/2012#0183;#32;The salt slag recycling process operated by Befesa rias Salinas SA enables the recovery of free metal and flux salts, thus creating a product made up mostly of aluminium oxide. The first stage of the process is the mechanical grinding, whose target is the extraction of metallic aluminium from the salt slag and the reduction of particles to an optimum size to ensure the total dissolution of the salts.
07/05/2018#0183;#32;Steelmaking plants continuously strive to reduce the environmental load in the steelmaking process, resulting in the recycling of energy, water, and other byproducts. In this chapter, techniques for the treatment and recycling of metallurgical slags are described. Metallurgical slags are considered secondary raw materials and are used or added during the process to improve steelmaking practice.

Recycling slag minimizes waste and disposal costs, reduces energy use, extends furnace life, and lowers the amount of additives needed to make slag. The concerns with slag recycling are that first, because slag can contain environmentally hazardous materials, it must be analyzed for elemental composition before reuse. Second, care must be taken to improve slag potential for other purposes without
