[3] [4] [7] [9] Andy Kelly of PC Gamer described Islands as reminiscent of the "nonsensical micro-dreams you have when you’re trying to stay awake while jet-lagged." [7] Similarly, Philippa Warr of Rock Paper Shotgun described the game's transformations as "more of a gentle dreamtime absurdity."
Electric phosphate smelting furnace in a TVA chemical plant (1942) Smelting is a process of applying heat and a chemical reducing agent to an ore to extract a desired base metal product. [1] It is a form of extractive metallurgy that is used to obtain many metals such as iron, copper, silver, tin, lead and zinc.
A bloomery is a type of metallurgical furnace once used widely for smelting iron from its oxides. The bloomery was the earliest form of smelter capable of smelting iron. Bloomeries produce a porous mass of iron and slag called a bloom. The mix of slag and iron in the bloom, termed sponge iron, is usually consolidated and further forged into ...
Integrated steel mill in the Netherlands.The two large towers are blast furnaces.. A steel mill or steelworks is an industrial plant for the manufacture of steel.It may be an integrated steel works carrying out all steps of steelmaking from smelting iron ore to rolled product, but may also be a plant where steel semi-finished casting products are made from molten pig iron or from scrap.
The Manufacture of Iron -- Filling the Furnace, an 1873 wood engraving. Many furnace designs for smelting combine ore, fuel, and other reagents like flux in a single chamber. Mechanisms, such as bellows or motorized fans, then drive pressurized blasts of air into the chamber. These blasts make the fuel burn hotter and drive chemical reactions.
Iron smelting—the extraction of usable metal from oxidized iron ores—is more difficult than tin and copper smelting. While these metals and their alloys can be cold-worked or melted in relatively simple furnaces (such as the kilns used for pottery ) and cast into molds, smelted iron requires hot-working and can be melted only in specially ...
Coke, limestone flux, and iron ore (iron oxide) are charged into the top of the furnace in a precise filling order which helps control gas flow and the chemical reactions inside the furnace. Four "uptakes" allow the hot, dirty gas high in carbon monoxide content to exit the furnace throat, while "bleeder valves" protect the top of the furnace ...
Later metallurgical analysis of the iron bloom shows evidence that the piece of iron had been produced by a smelting process that had formed large, dense, relatively slag-free bloom. The placement of this unprocessed iron in the pit evokes ethnographic comparison to iron smelting rituals that ensure the production of high-quality iron that ...
