A mineral is a name for a naturally occurring, inorganic substance that is not produced by living things and can generally form crystals . Water that springs up from the ground passes through mineral deposits, dissolving some of the surface salts (not just table salt—any metal and non-metal compound) from the Earth's solid mineral crystals.
The primary methods used to extract minerals from the ground are: Underground miningSurface (open pit) miningPlacer mining The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.
The process of erosion concentrates denser minerals, most notably gold, into deposits known as placers. Depending on the source of the erosion products, certain rare earth elements-bearing minerals, such as monazite and xenotime, can be concentrated along with other heavy minerals.

Lead facts. Lead is a soft, malleable, ductile and dense metallic element. It is extracted chiefly from the mineral galena and found in ore that also contains zinc, silver and copper. The chemical properties of lead allow this element to be used in power storage and delivery applications.
The froth is skimmed off and the resulting lead sulphide concentrate is dried. During this process, the ore, which may contain only 5% lead, is upgraded to a concentrate with 50% or more lead. At Broken Hill, concentrate grades average about 70% lead, mainly because the relatively coarse grain of the ore allows excellent recovery of lead sulphides.

The "ash content" is a measure of the total amount of minerals present within a food, whereas the "mineral content" is a measure of the amount of specific inorganic components present within a food, such as Ca, Na, K and Cl.Determination of the ash and mineral content of foods is important for a number of reasons:
Common mineral deposits in Hydrothermal are copper, lead, zinc, gold, silver, platinum, uranium and others. The relation ship between metamorphic activity and the formation of many ore deposits suggests that hydrothermal and igneous rock deposits should be especially common in regions of extensive magmatic activity.
