Ore
|
An ore is a type of rock that contains minerals with important elements including metals. The ores are extracted through mining; these are then refined to extract the valuable element(s). The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighted against the contained metal value of the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining. Metal ores are generally oxides, sulfides, silicates, or "native" metals (such as native copper) that are not commonly concentrated in the Earth's crust or "noble" metals (not usually forming compounds) such as gold. The ores must be processed to extract the metals of interest from the waste rock and from the ore minerals. Ore bodies are formed by a variety of geological processes. The process of ore formation is called ore genesis. From Wikipedia under the

In runescape buying iron and coal ore then smithing it into a steel bar is that a good way to make a profit? and how much gold of profit are you getting? Asked by Steve J - Sun Nov 16 15:27:34 2008 - - 6 Answers - 0 Comments A. Actually, smithing bars is just about the only way to make money while training smithing. Back before the GE, there were "companies" on the forums that would pay folks to smith steel bars at a fixed price per bar, and they would even provide materals. I believe that members can make smithing cash in other ways, like smithing cannon balls. I'm not familiar with current prices, but you will make some profit, though probably not as much as the classic money-making ways such as fighting cows or hill giants, chopping yews, or running rune ess. Just look at prices in the GE. Classic prices were like: coal (x2) - 175ea iron (x1) - 100ea total materials per bar - 450gp Sell bars for 550gp (about 100gp profit each).

For this, you require two-stage crushing plant, a primary reduction by a single jaw crusher. The output from the Jaw crusher at -40 mm than to be fed into Vertical-Shaft-Impactor (VSI). Since the material is abrasive in nature the VSI has to be rock-on-rock configuration. This will minmise your wear cost. You will require to put screen to seperate -3 mm to output, the above 3 mm particle will return to VSI for recirculation.
