The definition of ore is dependent on _____ Quantity Size Colour Quality. Engineering Geology Objective type Questions and Answers.
The microscopic study of ores has been extensive during the past forty years, but a satisfactory classifiion and definition of textural terms has not been forthcoming. A preliminary list of textural terms taken from the literature and arranged in groups according to origin is given herewith.
· Extraction of MetalsA metal is a material that is extracted from the ore. When it's been freshly prepared, polished, it shows a lustrous appearance and conducts electricity and heat relatively well. Metals are typically malleable (they can be hammered into thin sheets) or ductile (can be drawn into wires). Metals play vital roles in our daily lives; we almost use metals everywhere for ...
· Grindability of a dicing blade was estimated from dicing speed under constant feedingforce dicing process. Theoretical dicing speeds were calculated from the plowing speeds of abrasive diamond grains. It was concluded that grindability depends on the size, number and distribution of .

· Ore Minerals. An ore is a natural occurrence of rock or sediment which contains enough minerals with economically important elements, typically metals, that can be extracted from the deposit economically. The ores are extracted by mining for a profit from the earth; they are then refined (often by smelting) in order to extract the valuable ...
ore reserve (S) and the rate of extraction (q). Intuitively these two factors will inform decisions about the capacity of the mine, for the larger the rate of extraction the shorter will be the life of a mine for any given size of mineral reserve and vice versa. These two factors (S) and (q) also define the life of the mine (T). The present value (PV) for any mining operation is the sum of all ...
· Results show that a step change of new feed ore is detected in about 30 to 80 min depending on the grindability change. This result may be considered to be adequate when taking into account that the response time for the mill holdup to attain a new equilibrium value after the ensuing transient is of about 3 h.
An inconvenient consequence of adopting an economic definition of ore is that there is no longer any inherent property of the mineralised which permits an answer to this question in isolation. Although exploration personnel often calculate a 'dollar value per ton of rock' in order to assess target, in fact, minerals in the ground have no explicit value. Not until they have been extracted ...
· Grindability an overview ScienceDirect Topics. Grindability index is a measure of the ease of grinding of a given feed. Utility industries use the Hardgrove grindability index (HGI) to express this parameter. In the direct cofired system, the existing mills designed for .
