COAL By definition coal is a fossil fuel formed by plants and animal buried years ago‚ this formation facilitated by the high temperature and pressure underground. This mineral can be used as a solid fuel and as a raw material for coke and gas. After this lengthy process of formulation coal is recognized as a significant factor of the world’s manufacturing sector. As this is so‚ there is a global demand for this commodity. Ship being the suitable mode of transportation for this commodity‚

(such as copper carbonate) are called ‘copper ore’. Copper is extracted from copper ore by a series of chemical‚ physical‚ and electrochemical processes. Ores can be classed as ‘high grade’ or ‘low grade’ depending on the percentage of copper compounds (e.g. copper carbonate) they contain. After mining‚ the ore is crushed‚ roasted‚ smelted and then electrolysed to extract the copper. Suggested Equipment Boiling tube Samples of different carbonate ores‚ containing a range of percentages of copper

created within the solid ore and below‚ a transport and drawpoint drift are created. The orebody is also divided into separate stopes and are supported by the pillars. - To obtain the highest mining efficiency‚ stopes need to be as large as possible - Between each main level‚ blast patterns are drilled using the sublevel drifts. - The drill patterns specify where the blast holes are collared and the depth and angle of each hole. - The Blasted and broken ore is then transported using

Rod mill (ever identified as bar mill) is mostly utilised for raw materials processing and crushing‚ which include feldspar‚ quartz‚ ore‚ and so on. It is also appropriate for producing abrasive‚ fire-proof materials‚ cement‚ steel grit‚ slag powder‚ copper ore‚ iron ore‚ gold ore‚ concrete aggregate‚ asphalt aggregates and so forth. So this is a form rod grinder. It is mainly for medium and fine crushing of challenging‚ brittle components. There may be one more form dry rod mill. In order to prevent

1 Metallogeny: The rationale behind space (WHERE?) – time (WHEN?): distribution of ore deposits Whether there is any globally discernible unifying pattern about the space-time distribution pattern The exclusivity in spatial-temporal distribution of ore deposits is a tangible proposition Such distribution patterns are REAL and not apparent (not artifacts due to inadequate sampling) Such patterns can be explained in the light of the known/emerging facts about the evolution of the planet
