If not then try to scratch the Talc with your rock. You can do this with a simple and cheap UV light bought from a party supply store. If you have a voltmeter, you can take it all a step further. Additionally, with ultraviolet light certain rocks take an amazing glow, often different than the color of the light being projected on it. Aggregated diamond nanorods.

It seems surprising that mining engineers have gone along so many years without attempting, so far as I know, to make a more thorough study of the fundamentals of the business, and certainly the first thing in mining is to learn the mechanics of penetrating the rock so that you can place the explosive, and the next is the properties required to disrupt that rock. https://doi.org/10.5408/1089-9995-55.1.56, Winkler EM (2013) Stone: properties, durability in mans environment, 2nd edn.

This is done by multiplying the percentage of each mineral in a rock by the Moh mineral hardness and dividing by 100. OPTICAL BRINELL VIDEO MEASUREMENT SYSTEM. Int J Rock Mech Min Sci 75:159168. However, it has been found that these characteristics as determined by the Bureau of Public Roads methods have no constant relation to actual drilling speed. Other rocks can be at least melted at reasonable temperatures such as basalt. in. Grand Rapids, located in the lower peninsula has hard water according to USGS standards at 380 PPM. Quartzite is near the head of the list, yet quartzite in some places is fast-drilling and easy to break. It seems to me that the strength of the combination cannot be worked out by an analysis of the different minerals, because it depends largely on the bonding of those minerals. However, one who is familiar with the ground and with drilling operations can quite frequently closely estimate the speed at which a face can be drilled by observation and by testing the rock with a pick point. Are there bands in the rock? Bow Tie Guy and Wife. There exists, as may be seen from the foregoing table, a very definite relation between the hardness as here determined and the percentage of silica in a rock. I regret that I cannot endorse the suggestion of scales of hardness and toughness as a criterion in the matter. https://doi.org/10.1007/s11440-016-0467-3, Bakar MZA, Butt IA, Majeed Y (2018) Penetration rate and specific energy prediction of rotarypercussive drills using drill cuttings and engineering properties of selected rock units.

Our preliminary studies indicated that the work of the Bureau of Roads could not be used except with caution because its purpose is so entirely different from the problems in mining. https://doi.org/10.1007/s00603-006-0108-5, Tumac D, Copur H, Balci C et al (2018) Investigation into the effects of textural properties on Cuttability performance of a chisel tool. https://doi.org/10.1007/s10064-007-0116-z, Arikan F, Aydin N (2012) Influence of weathering on the engineering properties of dacites in Northeastern Turkey.
