copper smelters produced 2,360,000 metric tons of copper slag[10]. The use of copper slag in the preparation of antiray heavy concrete was made by the Eighth Metallurgical Construction Research Institute of China in the late 1970s [11].
Recycling of REEs could help alleviate the criticality of REEs and eliminate the balance problem. Currently, however, no REEs are functionally recycled. This thesis studied the timedependent behaviour of REEs in copper matteslag system in copper matte smelting conditions.
1/8/2008· Current options for management of copper slag include recycling, recovering of metal, production of value added products and disposal in slag dumps or stockpiles. Currently, copper slag has been widely used for abrasive tools, roofing granules, cutting tools, abrasive, tiles, glass, roadbase construction, railroad ballast, asphalt pavements, cement and concrete industries.
1/11/2020· A new process for recycling zinc and copper from the smelting slag of waste brass was investigated in this study. The zinc and copper present in the smelting slag were dissolved in a ZnCl 2 –NH 4 Cl solution system. To recycle copper, the lixivium was purified

This process is that copper slag with high amounts of matte depleted, tailings reduced to smelt copper antibacterial stainless steel, matte back to copper process. It can achieve the purpose of depleted copper slag, and maximize the use of slag to obtain the highest value products.
This thesis studied the timedependent behaviour of REEs in copper matteslag system in copper matte smelting conditions. The literature review investigated the resources, production and recycling of REEs as well as the distribution of elements during
Recycling of REEs could help alleviate the criticality of REEs and eliminate the balance problem. Currently, however, no REEs are functionally recycled. This thesis studied the timedependent behaviour of REEs in copper matteslag system in copper matte smelting conditions.
10/11/2020· Copper slag is a byproduct created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of nonmetallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.
Guadeloupe: a guide to recycling and use of inert waste in the construction industry Case Study In consultation with stakeholders in the construction and recycling sectors, BRGM has compiled the available information on inert waste that can be recycled by the construction sector in Guadeloupe, in a document that aims to encourage a more virtuous approach and promote the circular economy.
1. Introduction At present, almost t copper slag are produced while 1 t copper produced. 1) The cumulative stockpiling of copper slag has been up to 250 million tons. Plenty of solid wastes brought serious damages to environment. 2) With the continuous development of copper smelting technology, the smelting intensity and matte grade increasing, matte in copper slag also constantly improved ...
