platinum is a dense, stable and rare metal that is often used in jewelry for its attractive, silver like appearance, as well as in medical, electronic, and chemical applications due to its various and unique chemical and physical properties.
miners used chemicals, heat, and electricity to process more complex metal and mineral compounds. silver, for example, often occurs in the compound argentite (silver sulfide) or in lead compounds. historically, the key chemical processes included amalgamation with mercury and leaching in a solution of chlorine, sodium or calcium hyposulfite (lixiviation), or cyanide.

copper is one of the first metals to be used, largely because it occurs in metallic form at the surface. by 4000 b.c., it was being smelted from ores in israel and other parts of the middle east. copper is a malleable, ductile reddish metal, and is one of only two strongly colored metals (gold being the other).
it was used to make decorative items, such as gates. it is no longer made on a large scale, and the last manufacturer of wrought iron in the uk closed down in 1976. these days steel is used
it can easily be worthwhile to only use leather armor just to get the extra metal to get off the ground. beware that only pristine items can be smelted in a crucible: used tools, or weapons cannot (but armor now can be smelted, even when damaged).
an ore is an item (usually a type of unrefined metal) that can be mined from rocks or mineral veins using the mining skill and a pickaxe. items such as gems, clay, granite, and essences are not ores per se, however they are still discussed on this page as they can be obtained via mining. metal ores can be smelt into bars using the smithing skill. trivia the heaviest ore is lunar ore, and the

these electrons are used up in the cathodic reduction of nickel ions to form nickel metal, which deposits on the seed particles. the nickel particles are removed when they reach a suitable size. the success of the nickel hydrometallurgical process led to research for similar methods to recover other metals.
nickel: smelting extraction and purification nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. in many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.
