Based upon that oxidation number, an electronic configuration is also given but note that for more exotic compounds you should view this as a guide only.
به خواندن ادامه دهیدAffinity for Other Elements. Platinum has a high affinity for sulfur, arsenic, and other chalcogens. It often occurs naturally in ores that contain these elements, and understanding this affinity is important for its extraction and purification. Abundance and Sources - Typically found in alluvial deposits or in ores with other platinum group ...
به خواندن ادامه دهیدJust four mines (one in Russia and three in South Africa) account for 90% of the world's platinum production. As well as being extracted from platinum mines, this metal is also produced when nickel is refined. Luxury jewellers use platinum for their limited-edition pieces because they know this will increase the long-term value of their ...

به خواندن ادامه دهیدUses of Gold in the Ancient World. Gold was among the first metals to be mined because it commonly occurs in its native form, that is, not combined with other elements, because it is beautiful and imperishable, and because exquisite objects can be made from it. Artisans of ancient civilizations used gold lavishly in decorating tombs and temples, and gold …
به خواندن ادامه دهیدAny mineral that is found close to the surface (even up to (text{1 000}) (text{m})) can be mined using surface mining techniques. If minerals are found deeper, as is the case with most of the gold in South Africa, underground mining is …
به خواندن ادامه دهیدPlatinum extraction begins with the mining of ore from the Earth's crust, a task that often involves deep underground mines. Due to platinum's dense location …
به خواندن ادامه دهید1. Introduction. Platinum group metals (PGMs) are a group of six elements, namely iridium (Ir), osmium (Os), platinum (Pt), palladium (Pd), rhodium (Rh) and ruthenium (Ru) [1, 2].PGMs together with gold …

Let the learners choose one industry and research the different aspects of mining covered in this chapter for their chosen industry. The following mining industries can be researched: gold, iron, copper, diamond, phosphate, coal, manganese, chromium or platinum group metals (PGMs).
به خواندن ادامه دهیدThe underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.
