[ 3 ] [ 4 ] The game has a 2D sprite tile-based graphical style reminiscent of the 16-bit sprites found on the Super NES . [ 4 ]
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 .
The historical roots of metalworking predate recorded history; its use spans cultures, civilizations and millennia. It has evolved from shaping soft, native metals like gold with simple hand tools, through the smelting of ores and hot forging of harder metals like iron, up to and including highly technical modern processes such as machining and ...
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 ...
Modern TLS furnace used in copper smelting during heat up. Just as other industries have trended towards electrification , electric furnaces have become prevalent in metallurgy. However, while any furnace can theoretically use an electrical heating element , process specifics mostly limit this approach to furnaces with lower power demands.
This book describes smelting, which Agricola describes as perfecting the metal by fire. The design of furnaces is first explained. These are very similar for smelting different metals, constructed of brick or soft stone with a brick front and mechanically driven bellows at the rear. At the front is a pit called the fore-hearth to receive the metal.
Copper bells, axe heads and ornaments from various parts of Chiapas (1200–1500) on display at the Regional Museum in Tuxtla Gutierrez, Chiapas.. The emergence of metallurgy in pre-Columbian Mesoamerica occurred relatively late in the region's history, with distinctive works of metal apparent in West Mexico by roughly 800 CE, and perhaps as early as 600 CE.
