Slag is an item added by Thermal Expansion.It is obtained as a secondary output of smelting pulverized metals or dusts in an Induction Smelter.It can also be centrifuged from GregTech 4's Dark Ashes.The slag can be cooked in a furnace to make Rockwool, a block similar to Wool in that it can be dyed but is non-flammable. It can also be used to make Clay and various types of Florbs.

Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.
This will provide the bulk ores as well as a stream of slag. The slag and crushed stone can be crystalized as needed, but a lot should eventually go to mineralized water which is an important part of the algae and bioprocessing lines which lead to automated generation of the various forms of alien artifacts (useful for bob's and catalysts).
Slag is generated during smelting of tin concentrates through the f usion of ferrous silicate with limestone flux. Slag is collected when molten tin is tapped into a settler. Slag is believed to be resmelted and is therefore most likely not disposed as a solid waste. The Newly Identified Mineral Processing Waste
Covers the production, processing, and utilization of a broad range of ferrous, non-ferrous, and non-metallurgical slags; Provides information on applicable methods for a particular slag and its utilization to reduce potential environmental impacts and promote natural resource sustainability
Abstract- Tin slag a waste product of tin smelting contains many important metals such as niobium, tantalum, manganese, iron, aluminum, titanium, etc. Niobium metal which is one of the important metals found in tin slag has successfully been extracted using leaching and electrothermal method. The tin slag
In Brazil, Malaysia and Thailand,the tin industry provides tantalum as a component of the tin slag by-product, that arises from the smelting of cassiterite ore concentrates for tin production. Struverite concentrates (a Ti-Nb-Ta mineral) have historically also been available from northern Malaysia containing 9-12% tantalum oxide.
With tin and Lead the dross can also be removed by adding sodium hydroxide pellets, which dissolve the oxides and form a slag. Dross is distinguished from slag, which is a (viscous) liquid floating on the alloy, by being solid. Lead Dross shall consist of slag, dross, skimming or spilling from Lead melting operations. A scum formed on the ...
trial processing that is a material form in which tantalum is recycled) and tantalum-containing tin slag concentrates, both of which can enter the supply chain along with tantalum concentrate produced from tantalum ore. Further processing produces tantalum metal powder and other tantalum-containing materials. Tantalum metal is further processed ...
Tin smelters produce considerable amount of slags along with metallic tin. This slag can be turned in to a valuable by-product if the refractory metals like niobium, tantalum, zirconium and ...

Gold and silver form an alloy that is heavier than the slag and sinks to the bottom of the furnace. Once the smelting is complete, the slag is removed and the precious metals are casted in ingots. The slag contains gold and silver and must be reprocessed in order to minimize the losses of precious metals.
of these tin-processing companies and (or) plants and therefore cannot verify whether these facilities consumed tin concentrates and, if so, whether or not those concentrates were sourced from conflict-affected areas. Other forms of tin such as recycled products, tin slag, tin scrap, or intermediate products may be used as source materials.
The ability to fire assay a substance relies on a number of facts. First of all, the samples that contain gold and silver should be solubility in molten metallic lead and that gold and silver are insolubility in slag. Fire assay also relies on the difference in specific gravity between the two liquids, the molten lead and the slag.
Lead processing: Lead processing, preparation of the ore for use in various products. Lead (Pb) is one of the oldest metals known, being one of seven metals used in the ancient world (the others are gold, silver, copper, iron, tin, and mercury). Its low melting point of 327 °C (621 °F), coupled with its easy

12.3 Primary Copper Smelting 12.3.1 General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams (Mg)
The initial processing of tin slag was authorized in April 1967, but full-scale processing did not commence until late 1967 or early 1968. On March 18, 1968, the State of Pennsylvania authorized disposal of slag waste containing natural thorium and uranium at the slag pile site.
The tin concentrate is placed in a furnace along with carbon in the form of either coal or fuel oil. It is heated and forms a slag along with the crude tin. The slag and crude tin are heated several more times to remove impurities and recover tin hardhead.
