The game was developed and published independently by artist and animator Carl Burton, best known for the animated GIF illustrations he created for season two of the Serial podcast. [3] [13] Islands was released on November 17, 2016, on Windows, macOS, iOS, and Linux.
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 ...
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 ...
Induction furnaces do not require an arc, as in an electric arc furnace, or combustion, as in a blast furnace. As a result, the temperature of the charge (the material entered into the furnace for heating, not to be confused with electric charge ) is no higher than required to melt it; this can prevent the loss of valuable alloying elements.
The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron ().The process combines two process units, the Cyclone Converter Furnace (CCF) for ore melting and pre-reduction and a Smelting Reduction Vessel (SRV) where the final reduction stage to liquid iron takes place.
The player moves around the 2D world, and can climb and jump up objects. The player can use a tool, the Omni Switch, which allows Mo to use mechanisms and solve puzzles. The tool also can show the player the direction they need to go to next. The game also has collectibles hidden around the islands, which reveal more about the world and story ...
Iron production continued to increase; the Weald in the South-East began to make increased use of water-power, and overtook the Forest of Dean in the 15th century as England's main iron-producing region. [27] The first blast furnace in England, a major technical step forward in metal smelting, was created in 1496 in Newbridge in the Weald. [28]
