How Does Marble Get Mined From a Quarry? Sciencing

Apr 24, 2017 0183 32 Once mining has begun, there may be several months of digging before any marble is extracted from the quarry Overburden, or dirt on top of the desirable ore, needs to be extracted before blocks of marble can be removed In addition, establishing roads or tunnels for vehicle access is critical to the profitability and efficiency of the mine...

Genetic Model of Ore Deposits Mining Engineering Science

May 19, 2015 0183 32 SEDEX ore deposits are formed due to concurrent release of ore-bearing hydrothermal fluids into aqueous reservoir mainly ocean, resulting in the precipitation of stratiform zinc-lead sulfide ore in a marine basin environment The stratification may be obscured due to post depositional deformation and remobilization...

Ore Body Modelling

An ore body model has three distinct components, viz i the physical geometry of the geologic units that formed and host the ore body ii the attribute characterisation in terms of assays and geo-mechanical properties of all materials to be mined and iii the value model in terms of economic mining of the ore ,...

Classification of Mineral Deposits Geology for Investors

Geologists, are known to have more opinions than economists, so it should come as no surprise that the classification of mineral deposits, is an on-going hot topic The details will be debated until the sun cools, but the broad-brush classification of mineral deposits is generally understood Most ....

Porphyry geology

Porphyry is a textural term for an igneous rock consisting of large-grained crystals such as feldspar or quartz dispersed in a fine-grained silicate rich, generally aphanitic matrix or groundmassThe larger crystals are called phenocrystsIn its non-geologic, traditional use, the term porphyry refers to the purple-red form of this stone, valued for its appearance...

Resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model There are different estimation methods see below used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available...

Sedimentary Ore Deposits Mining Geology

Sedimentary deposits are formed through the erosion, transportation, and redeposition of minerals that can survive the rigors of transportation The most common is silica, which forms a number of materials, including silica sand, sand and gravel, and flint The precursor is igneous quartz eg, in granite , and then the sedimentary deposit may undergo metamorphism and recementing to produce ....
