Geologists identify minerals by their physical properties. In the field, where geologists may have limited access to advanced technology and powerful machines, they can still identify minerals by testing several physical properties: luster and color, streak, hardness, crystal habit, cleavage and fracture, and some special
Following the rapid escalation over the past decade in the worldwide demand for platinum-group elements (PGE), in particular platinum and palladium, together with the high …
For a substance to be a mineral, it must be a naturally occurring, inorganic, crystalline solid that has a characteristic chemical composition and crystal structure. The atoms in minerals are arranged in regular, repeating patterns that can be used to identify that mineral. Minerals are divided into groups based on their chemical composition.
RESTON, Va. — The U.S. Geological Survey has invested more than $2 million from President Biden's Bipartisan Infrastructure Law in cooperative agreements with 14 states to study the potential for critical mineral resources in mine waste. This funding will allow the USGS and these states to better map locations of mine waste and …

Learn all about platinum as a precious metal, and the centuries long processes of mining and refining that have made it so integral to many parts of the world. Enjoy a detailed discussion on the history of platinum mining and refining, including facts, figures, pictures and charts to help explain.
This paper provides a review of existing research literature and thought on sustainability in mining of non-fuel minerals. A common sustainable mining framework is focused on reducing environmental impacts of mining.
My collection includes some minerals that I self-collected underground in the Tri-State District, Pea Ridge Mine, Sweetwater Mine, Brushy Creek Mine, Buick Mine, Elmwood Mine, numerous surface deposits, quarries and road cuts. Field collecting is still a love of mine, even though the places that grant permission to collect are ever dwindling.
Platinum-bearing intrusives of forsterite dunite are the source rocks for several types of platinum deposit, broadly grouped as late magmatic and placer. Only minerals of the platinum group are of … Expand
This paper takes its starting point in the fact that many mines have managed to improve its work environment, with regards to, for example, accident occurrence, while at the same time having stopped seeing improvements in these areas even in the wake of technology interventions. Technology projects in the mining industry continue to make …
Zimbabwe is endowed with over 63 Minerals including Gold, Lithium, Platinum, Coal, Chrome, Copper, Diamonds ... making it a heaven for mining investment.
Silver ore refers to natural deposits of silver-containing minerals that are mined and processed to extract silver metal. Silver is a precious metal known for its lustrous appearance, high thermal and …

Spectral Signatures. Spectral analysis plays a key role in identifying valuable asteroids for mining. By analyzing the light reflected off asteroids, scientists can determine their spectral signatures, which indicate the types of minerals and compounds present on their surface.
Minerals & Rocks; How to Identify Platinum in Ore Deposits ... In South Africa, where the greatest mine production occurs, the mineral cooperite represents a chief source of platinum. The geological structure for the ore in South Africa is an intrusion called the Bushveld Complex. Platinum also coexists with diamonds.
Formula: Pt. Colour: Steel grey to dark grey. Lustre: Metallic. Hardness: 4 - 4½. Specific Gravity: 14 - 19. Crystal System: Isometric. Name: From Spanish "platina", diminutive of …
Mining Claims A mining claim is a parcel of land for which the claimant has asserted a right of possession and the right to develop and extract a discovered, valuable, mineral deposit. This right does not include exclusive surface rights (see Public Law 84-167). There are three basic types of minerals on federally-administered lands: locatable, leasable, …
