Compounding these above-the-ground risks is the fact the three constituent parties involved in mining have their own, often competing, agendas. National governments primarily seek tangible economic
Zircon is a zirconium silicate mineral with a chemical composition of ZrSiO4. It is common at some point of the world as a minor constituent of igneous, metamorphic, and sedimentary rocks. It is a popular gemstone that has been used for almost 2000 years. It takes place in a huge range of colours and has a brightness and hearth that competitors ...
The Wirlong prospect is located within EL8307 "Sandy Creek" and EL8126 "Norma Vale". It was once part of the Cobar Superbasin Project (CSP), along with other prospects including Sandy Creek, Red Shaft, Armageddon and Bedooba.In 2020, Peel regained ownership of CSP including Wirlong, when Japanese Oil Gas and Metals National Corporation (JOGMEC), sent a written notice to Peel ...
Mining chemicals represent a niche area of supply but at the same time their use is almost universal across the industry. In this month's im-mining Spotlight Feature Article, from the June issue of International Mining magazine, Editor Paul Moore looks at the players, challenges, and future horizons for the sector.

Silica sand is a very fine sand composed of quartz (a white to colorless mineral) and is mined in the southeastern part of Minnesota. It is used to make glass, as a source of silicon, and is used in oil drilling to improve the flow of oil to oil wells. Granite and limestone are used in the construction of homes, buildings, roads and tombstones.

Silica (silicon dioxide, SiO 2) occurs as the mineral quartz, a major constituent in many igneous and sedimentary rocks, and the most common detrital mineral in sandstone.As a commodity, the term silica is applied to quartz in all its forms — as vein or reef quartz, quartz pebbles, sandstone, quartzite, or as unconsolidated sand.
The zinc content of mined ore is usually between 3 and 10 percent. Almost all ores contain the lead sulfide mineral galena and small quantities of cadmium sulfide. Chalcopyrite, and copper-iron sulfide, is often present. The most common gangue constituents are calcite, dolomite, and quartz. Mining …
Mining wastes include waste generated during the extraction, beneficiation, and processing of minerals.
