First human colonies in space will be composed of mines
Imagine the first human colonies in space. The futurist Tom Cheesewright already did it and, according to him, these colonies will include little more than a few mines, oil rigs and manufacturing outposts to refine minerals. That being said, Cheesewright adds that asteroids are probably more likely to be the first “places” to receive long-term colonisation projects. The futurist’s company, called Book of
Mining and other industrial activities are destroying coral reefs and causing sea life extinction
A new research made by the University of Florida shows that modern species living in reef habitats that are quickly declining, like Australia’s Great Barrier, are likely to be at risk. The document reached this conclusion after several ancient crustaceans went extinct due to a massive collapse of coral reefs across the planet, showing a direct relation between the amount of prehistoric reefs
Flotation of Marmatite
The chemical formula for sphalerite and marmatite is (Zn,Fe)S not (ZnFeS2). The iron and solid solution are in a solid solution and marmatite (there is technically no mineral called marmatite) is referred to as the high iron variety of sphalerite https://en.wiktionary.org/wiki/marmatite They have the same flotation properties and the high iron content makes the sphalerite almost black. Their was

Albion VS Activox Comparison of Gold Refractory Process
Each of these Gold Refractory Process aim at the oxidation of sulphide minerals and utilizes a combination of fine grinding (3 to 9 microns) under mild conditions. Activox is a low temperature (90-100°C), low pressure (1000kPa) process. Albion is a low temperature (90-95°C), atmospheric pressure process. Albion’s reactor is not “just a tank”. It is specially design to optimize oxygen injection for
