Note: The main difference between tinstone ore and wolframite ore is that tinstone ore is not magnetic while the latter is magnetic. Thus, Wolframite ore is separated from tin stone ore by the process of electromagnetic separation and the correct answer to the question is option (b). It is basically thermal decomposition of ores and other materials. Calcination is the process of heating ores at high temperature in the presence of air or oxygen. This process uses heat and chemical reducing agents to decompose the ore, and driving off other elements and leaving only the metal base behind. Many metals are extracted from their ores using this method like silver, iron, copper and other base metals. ![]() Smelting is a process where metal is extracted from an ore by applying heat. Roasting consists of oxidation, reduction, chlorination, sulfation and pyrohydrolysis reactions. It is a metallurgical process involving gas-solid reaction at high temperatures and used to purify metal components. Roasting is a process of heating of a sulphide ore at a high temperature in the presence of air. ![]() It is a method to purify certain metals, ores, isolate metals and oils. Electromagnetic separation is a process of removing magnetic materials from non magnetic materials, using electromagnets in which the materials travel along a conveyor, over a drum or into a revolving screen. General Chat Eternal Lands Official Forums. Because wolframite has a magnetic nature, it can be separated from tinstone using an electromagnetic separator. The ingreds given in the message about the new spells for wolframite bars isn't correct Jump to content. It has the same mass per unit volume as that of a tinstone. ![]() It is present in tin stone as impurities. Wolframite ore can be represented as\\]. Hint: Wolframite is an ore of iron and tungsten.
