Mineral resource estimation - Wikipedia

Mineral 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 used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available.

The Learning Zone: What is a Mineral?

A mineral is a naturally occurring inorganic solid, with a definite chemical composition, and an ordered atomic arrangement. This may seem a bit of a mouthful, but if you break it down it becomes simpler. Minerals are naturally occurring. They are not made by humans. Minerals are inorganic.

Does A or B grade matter?-541 - Crystal Recommendations

· A grade stones are not necessarily "better" than the B grade stones, however sometimes the A grade stones are more clear and pure and thus have a stronger vibration. B grade stones can be very useful and I suggest that you experiment with them and see how they feel different to you. It is important to clear your stones regularly and we have an article here that discusses methods for

Station 2. Luster is the way a mineral's surface reflects light. Play the video to see examples of common mineral luster. Station 3. Hardness is the ability for a mineral to resist being scratched. In 1812, German Scientist Friedrich Mohs developed a scale to test hardness of a mineral. He found ten standard minerals that others can be tested on.
