The economic deposits of cassiterite are known in two types of geological occurrences primary vein or hard-rock deposits and secondary placer deposits (Falcon, 1982, Rao, 1992). The mineral assays about 0.4–1.5% Sn (occasionally 5–6%) in the hard-rock deposits and placer deposits are slightly poorer in grades (Bulatovic, 2010).

Coastal placer mineral deposits are known from shorelines of several countries world over. However, distribution of significant beach placer deposits being restricted to tropical-subtropical belts of the world (Fig. 2.1).Such deposits occur in east and west coasts of Australia, southern part of China, Sri Lanka, Malaysia, Madagaskar, Worldwide there are over 43 million artisanal miners in virtually all developing countries extracting at least 30 different minerals. Gold, due to its increasing value, is the main mineral extracted by at least half of these miners. The large majority use amalgamation either as the final process to extract gold from gravity concentrates or from Free Full-Text Gravity Concentration in Artisanal Gold Mining

Idiomorphic chromite is the only ore mineral appearing in economic quantities. The average content of the ore is 26% Cr 2 O 3 and the Cr/Fe ratio is 1.55. The Kemi chromium mine is an open-pit mine with a waste rock to ore ratio of 5.5:1. At Kemi, the ore from the mine contains 11% iron and 25.5% Cr 2 O 3.NioCorp is developing the niobium /scandium /titanium Elk Creek carbonatite deposit. The probable reserve announced by the company in 2017 indicated significant niobium (0.79% Nb 2 O 5), titanium (2.81% TiO 2), and scandium (71 g/t), and is composed predominantly of calcite, dolomite, and ankerite.Niobium is mostly (80%) A Process Flowsheet for the Extraction of Niobium, Titanium,

Abstract. Flotation is the most effective solution, both technologically and economically, when upgrading iron concentrates. Research regarding iron ore flotation began in 1931, demonstrating thatA processing flowsheet includes magnetic separation, milling and gravity concentration methods. The separation technology provides for production of iron ore concentrate with total iron content of 65.9% and recovers 91.0% of magnetite and 80.5% of hematite from the tailings containing 20.4% of total iron.Recovery of magnetite-hematite concentrate from iron

Abstract. The concentration of rare earth element in any geological environment alone does not make it suitable for commercial mining. The ease of exploitation is commonly dictated by favourable geological setting, ore grade, tonnage, existing processing technology, costs and attendant environmental concerns including local people.Placer Golds. Among free-milling gold ores placer gold is a special case, as there is no pre-treatment required for gold extraction.

Placer Deposit Processing. The handling of large quantities of gold-bearing gravels is of utmost importance for most successful placer operations. In addition to providing efficient washing and recovery methods, the placer plant should be constructed as a compact unit that can be readily moved.

Analysis of the current technical solutions for the processing of iron ores showed that the high-grade ores are directly exposed to metallurgical processing; by comparison, low-grade ores, depending on the mineralogical and material composition, are directed to beneficiation including gravitational, magnetic, and flotation processes or their The mineralogical study of gold has shown that gold ores may be classified in many ways: placer deposits (alluvial, eluvial, colluvial, and paleo-placer) (Marsden and House, 2006).(PDF) Mineralogical study and enhanced gravity separation
