source:Phys.orgAn international team of chemists has successfully created methylenedistibiranes, which are three-membered rings that have two antimony atoms and one carbon atom. In their paper published in the Journal of the American Chemical Society, the group describes how they were able to make the rings using just a three-step process.Methylenedistibiranes are generally used as intermediaries due to their ability to promote selective nucleophilic substitution, resulting in the creation of diantimonyl anions. Chemists have been wanting to be able to create them because it is difficult to us...

source:Linnaeus UniversityNew research shows that magnesium and other metals in mine waste can be solubilized and recovered thanks to acid-producing bacteria. Researcher Nathan van Wyk believes that the method has great potential for reducing environmental pollution, extending the life of mines and providing raw materials for industry.Each year, more than three billion tons of metal are produced for use in various products. However, the metal content of ores has decreased with exploitation, which has made it more difficult to access the metals. This has resulted in increased metal prices and m...

source:resource worldDefense Metals Corp. [DEFN-TSXV, DFMTF-OTCQB, 35D-FSE] Executive Chairman Guy de Selliers says the company is poised to make significant progress in developing its “world-class” Wicheeda rare-earths deposit in British Columbia.Whiceeda is an advanced mineral project with a measured resource of 6.4 million tonnes, averaging 2.86% total rare earth oxides (TRE0), including an indicated resource of 27.8 million tonnes averaging 1.84% TREO, and an inferred resource of 11.1 million tonnes, averaging 1.02% TREO. The project is located 80 kilometres northeast of the City of Prince...
