Glass ceramic is a material with both crystalline and amorphous states which is formed by controlling the crystallization process of a specific composition of basic glass through a definite heat treatment process [20] Glass slag can serve as the base glass for manufacturing glass ceramics thus it is necessary to understand the glass
Copper slag is generated when copper and nickel ores are recovered from their parent ores using a pyrometallurgical process and these ores usually contain other elements which include iron

The former process is preceded by a slag granulation procedure to facilitate recovery The product of this process is a concentrate which must go through the entire process of smelting and converting Typical copper electrolyte solution produced from leaching of copper ore contains 25 60 g/L of copper and 10 g/L of iron in the
Copper slag Iron ore tailings IOT and M Sand MS were the materials used as partial replacements for river sand among them Copper slag and Iron ore tailings were used as in replacement levels
The copper slag produced by the smelting industry contains valuable metals like Cu Fe Zn Pb Co and Ni along with harmful components like As Hg Bi and Sb However over 80% of global copper slag is discarded without proper disposal wasting valuable metals and harming the environment Phiri et al 2022 While some copper slag has been
Copper Slag in Bangladesh The Copper Slag can be an abrasive blasting grit composed of granulated Slag made out of metal smelting procedures The Slag made available from this process is deemed well suited for blast cleaning of metal and stone/concrete surfaces and removing mill scale rust old paint grime etc
Copper is a metal that is widely used in different applications mainly due to its thermal and electrical conductivities together with its corrosion resistance particularly when it is alloyed This chapter intends to be a summary of the copper metallurgy from the historical aspects and mineral deposits or statistics to the different technologies used to produce metallic
Mined ore which has a copper grade of less than 1% is turned into copper concentrate with a purity of about 30% at mine site and transported to the Toyo Smelter & Refinery In addition to copper copper concentrates contain about 30% each of iron and sulfur and trace amounts of gold silver and other precious metals all of which are recovered
One of the stages of extracting gold and platinum from sulfide materials and circulating slags is the melting stage in ore thermal and electric furnaces where the melt is separated into matte and slag Gold platinum and non ferrous metals are concentrated in the matte However a significant portion of them ends up in the slag which reduces recovery and

Copper plays a vital role in modern life which is irreplaceable for daily infrastructure and technologies [1] [2] However despite the finite copper resources on the Earth global copper production continued increasing over the past century [3] [4] Although we are far from approaching geological stocks for potentially mineable Cu resources the economic
The metallic particles are alloys and can be divided into three categories by the abundance in descending order 1 Gold > silver copper Figure B 2 silver > gold copper Figure C and c copper > gold silver Figure D The first category particles colored yellow contain the greater amount of gold than silver and copper
Copper slag is characterized by its high hardness and decent spray de rusting effect indicating its suitability as a de rusting abrasive Therefore copper slag is used as an abrasive for steel surfaces and as a de rusting agent in shipbuilding ship repair mechanical processing and manufacturing and petroleum and chemical industries
In the smelting and conversion processes of copper manufacturing copper slag with 2 3 times of crude Cu is produced Phiri et al 2022 a novel scheme for processing copper slag was proposed Fig 7 During actual processing steel slag was added to copper slag to adjust its acidity coefficient mass ratio of silica and alumina to
The copper slag is produced during the process of smelting for sulphide ore and collected as the material that floats on the top of the molten copper in a furnace This material ultimately turned into glassy solid after cooling and discarded as waste in dump yards Gold tailings are solid waste discharged during gold ore sorting operations
1 Small investment in equipment 2 Large processing capacity and low production cost 3 The solution adopts jigger to treat copper smelting slag with high recovery rate and high purity of the resulting copper alloy
Copper slag CS is a solid waste produced during copper smelting mainly containing 30 40 % Fe % Zn and other trace amount metal elements Shibayama et al 2010 Gümüşsoy and Başyi̇ği̇t M Uzun Kart E 2023 It is reported that China currently produces over 60 million tons of CS annually and possesses a stockpile of 130 million tons of
