Apr 26 2018 · Ores are naturally occurring rocks that contain metal or metal compounds in sufficient amounts to make it worthwhile extracting them For example iron ore is used to make iron and steel Here we providing a List of some Important metals and their ores it is mainly useful for your upcoming competitive exams like SSC UPSC etc

Zinc ore and mines Mineralisation The lead zinc and copper veins on Mendip were deposited by hot mineralising fluids typically between 50 and 150 ° C rising up from depth and depositing various minerals as they cooled The source of the fluids were the deep sedimentary basins either side of the Mendips Zinc ore occurs in two types of

Dec 21 2016 · A list of important metals with ores is given in this article which will give an idea of metals and from where they are extracted It will help in your

Hematite is the most important iron ore The iron content of the pure minerals is as follows Ankerite is a carbonate of lime magnesia manganese and iron It is of valuable composition carries only 14 or 15 of iron and is used more for its lime and magnesia as a flux than for its ironcontent

A Iron ore lead and copper B Chromium cobalt manganese and nickel When metal prices rise sharply this spurs immediate development of new mines which then begin production in a year or two TrueFalse US stockpiling of strategically important minerals may in the near term require the country increase some mineral imports

The ability to fire assay a substance relies on a number of facts First of all the samples that contain gold and silver should be solubility in molten metallic lead and that gold and silver are insolubility in slag Fire assay also relies on the difference in specific gravity between the two liquids the molten lead

Nickel was first discovered in 1750 It is manufactured from its sulfide ore named pentlandite NiFeS The ore is first concentrated by froth flotation process and then roasted and smelted like other nonferrous metals Nickel Properties Following are some important properties of nickel 1

Chalcopyrite is the most important source of ore for An igneous intrusion that forms between two layers of sedimentary rock is called a but high pressure cannot lead to recyrstallization because pressure only affects the shape of the crystals and not their arrangements

Lead Like copper lead is a malleable metal with a history spanning centuries Widely available and simple to extract the metal was The earliest known lead artifacts beads found in the Catalhoyuk region of what is today Turkey date back to 6400 BCE The Roman Empire was the largest producer of lead in the ancient world

properties of lead it is important to comply with the standards set out for the specific building or architectural applications 23 CHEMICAL PROPERTIES 231 EXTRACTION OF LEAD FROM ITS ORE The most common ore of lead is galena lead sulphide PbS Extraction of metallic lead from this compound is relatively easy

Uses of Galena Galena is a very important mineral because it serves as an ore for most of the worlds lead production It is also a significant ore of silver Galena has very few uses beyond its service as an ore but that should not diminish its importance to society

Lead is a dense soft lowmelting metal It is an important component of batteries and about 75 of the worlds lead production is consumed by the battery industry Lead is the densest common metal except for gold and this quality makes it effective in sound barriers and as a shield against Xrays
