· The digging of tunnels and sink shafts when the ore—or mineral deposit—is below the surface. Hand tools such as chisels, hammers, and wedges are used to break up waste rock, Sometimes, areas must even be blasted in order to loosen rock so workers can more easily separate the ore from the waste rock—which are mined separately.
Iron ores generally have higher grades than sulphide or gold ores, often going over 50 per cent or more. Less tailings are therefore generally produced in iron ore projects. After separating the valuable minerals, the tailings are often pumped in a slurry through pipes to be deposit…
quantities of high-grade mineral ore deposits. 1.1.2 Development If the mineral ore exploration phase proves that there is a large enough mineral ore deposit, of sufficient grade, then the project proponent may begin to plan for the development of the mine.
To find an ore deposit, geologists will go to a likely spot. They then test the physical and chemical properties of soil and rocks. Ore deposits contain valuable minerals. They may also contain other chemical elements that indicate an ore deposit is nearby. After a
· Modified seawater is the dominant ore fluid in the type of deposit we choose to call VMS (Franklin et al. 2005). Arcs have better access to seawater than intracontinental rifts and thus would tend to be dominated by seawater and form VMS deposits, whereas intracontinental rifts would tend to circulate brines and form SEDEX deposits.

Only iron and steel rust. Other metals corrode. Rusting is an oxidation process. What we normally call rust is a flaky red-brown solid which is largely hydrated iron.The primary corrosion product of iron is Fe(OH)2 (or more likely FeO.nH 2 O), but the action of oxygen and water can yield other products having different colors: ...
· Leading Iron Ore Producing Countries Much of the iron ore are in the sedimentary rocks called Banded Iron Formations (BIFs), which dates back to more than 542 million years. They are present in all continents and mined as iron ore or rocks containing iron ore.
· Here I describe the close association of epithermal deposits with nearby porphyry deposits, where we find them globally and show why epithermal deposits are economically worth paying attention to. The bulk of the course will cover different types of epithermal deposits, how each of them are formed and I''ll finish up as usual with a short section, on how we explore for these deposits .
