The "Acid Test" for Carbonate Minerals and Carbonate Rocks

The Acid Test on Rocks. LIMESTONE, DOLOSTONE, AND MARBLE. Some rocks contain carbonate minerals, and the acid test can be used to help identify them. Limestone is composed almost entirely of calcite and will produce a vigorous fizz with a drop of hydrochloric acid. Dolostone is a rock composed of almost entirely of dolomite. It will produce a very weak fizz when a drop of cold hydrochloric ...

MSHA - Rock Dusting Information - MSHA Rock Dusting ...

REMEMBER - The chance of propagation and risk of widespread explosion disasters in bituminous coal mines can be nearly eliminated when rock dust is applied liberally and maintained properly. However, unless rock dusting is appropriately and properly maintained, it will almost surely fail in an emergency.

Glossary of Mining Terms

Amorphous - A term applied to rocks or minerals that possess no definite crystal structure or form, such as amorphous carbon. ... Dilution (mining) - Rock that is, by necessity, removed along with the ore in the mining process, subsequently lowering the grade of the ore.

Measuring and modelling of dry bulk rock density for ...

AbstractRock density information is needed for the estimation of ore tonnage, and also for determining the amount of contained metal; this is because mineralisation grades are usually reported as a ratio of the economically viable components, metals or minerals, to weight units (e.g. grams/tonne). Despite the obvious importance of rock density for the accurate estimation of tonnage and grade ...

Rock mechanics applied to shaft pillar mining - SpringerLink

The Bureau of Mines is investigating methods for evaluating and optimizing shaft designs for deep metal mines. This paper describes one such project at the Homestake Mine in Lead, SD. To determine a safe approach for the extraction of ore from the Ross Shaft pillar at Homestake, a basic rock mechanics approach has been taken that involves laboratory testing, field measurements, and computer ...

Rock Mechanics - an overview | ScienceDirect Topics

Rock mechanics is the study of the mechanical behavior of subsurface sedimentary strata and rocks that are formed. The basic principle is that rock simply responds to stress by changing in volume or form. The change in the rock volume or form due to the applied stress is called strain. Rocks subjected to compressive stress (+) or tensile stress (−) can go through three stages of strain ...
