Surface color may be helpful in identifying minerals although it can be quite variable within the same mineral family Mineral colors are affected by the main elements as well as impurities in the crystals These impurities may be rare elements—like manganese titanium chromium or lithium—even other molecules that are not normally part of the mineral formula
·There are chapters on the ore microscope and preparation of samples qualitative methods of mineral identification reflected light optics ore mineral textures and on the qualitative methods for
·Mineral processing operations generally follow a set of specific steps to separate ores into products rich in valuable minerals concentrate and waste streams The breakdown of the mineral processing steps within the mining chain is illustrated in Fig 3 Run of mine ore undergoes an initial process of crushing milling and classification to
·Mineral processing is a form of extractive metallurgy that separates valuable minerals from the ore into a concentrated marketable product Mineral processing is also known as mineral dressing Mineral processing is conducted at the site of the mine and is a highly mechanical process with oversight from a central control room
·Mining mineral processing and metal extraction are undergoing a profound transformation as a result of two revolutions in the making—one advances in digital technologies and the other availability of electricity from renewable energy sources at affordable prices The demand for new metals and materials has also arisen concurrently This necessitates

Platinum jewelry is rare beautiful and durable and is therefore highly regarded Native Platinum is the most significant source of the element platinum although considerable quantities are also mined from the rare platinum arsenide mineral Sperrylite The rare metals iridium osmium rhodium and palladium are almost exclusively mined
·About 80% of the worlds reserves for platinum group metals PGMs are in South Africa s Bushveld Igneous Complex Processing of PGM involves comminution flotation smelting converting base metals refinery and precious metals refinery Due to increasing chrome content in the feed and the challenges associated with operating high chrome feed alternative
A typical learning pathway in this field would start with this qualification and proceed to the National certificate NQF Level 3 Mineral Processing Gold Platinum Metals Uranium Mineral Sands Base Metals Extraction and Lump Ore Beneficiation and Supervisory management and leadership competencies
Chemical Composition Nearly all % of Earth s crust is made up of only eight elements oxygen silicon aluminum iron calcium sodium potassium and magnesium and these are the elements that make up most All minerals have a specific chemical composition The mineral silver is made up of only silver atoms and diamond is made only of carbon atoms but
