how is cassiterite concentrated Solutions Just Right For You

Cassiterite is SnO₂ This method is based on the difference in the specific gravities of metallic ores and the gangue particles and is therefore used when the ore particles are heavier than the earthy or rock gangue particles Related Questions: The reaction between an This has led to cassiterite being considered a conflict mineral Cassiterite is a widespread minor constituent of igneous rocks The Bolivian veins and the old exhausted workings of Cornwall England are concentrated in high temperature quartz veins and pegmatites associated with granitic intrusives

CASSITERITE AND RUTILE AS INDICATOR MINERALS FOR

Cassiterite and rutile strongly resist physical and chemical weathering and can be used as indicator minerals for mineralisation These minerals are residually concentrated in a near-surface silcrete duricrust capping a deeply weathered profile developed over the Scuddles Cu-Zn-Pb VMS deposit Golden Grove Western Australia

Vein and disseminated tin deposits are mined by the same methods used in hard-rock mining of other non-ferrous ores such as zinc The ore is broken by drilling and blasting transported to a concentrator where it is crushed and ground and then concentrated by gravity methods

Cassiterite is concentrated by - Tardigrade Cassiterite is concentrated by (A) Levigation (B) Electromagnetic separation (C) Floatation (D) Liquefaction Check Answer and Solution for above question from Chemistry in General Principles and Processes of Isolation of Elements - Tardigrade

This partly resulted from the resistance of cassiterite to acid attack commonly used for chemical decomposition of minerals Furthermore the solution containing Sn requires careful handling because Sn is readily oxidized and precipitates in concentrated nitric acid as hydrous stannic oxide or metastannic acid 3 Sn + H 2 O + 4HNO 3 = 3 H 2

Tin Ore Extraction

The flowsheet below Explains the Extraction of Tin Ore as shown by a study adapted to the concentration of a lode tin deposit Cassiterite (SnO2) is very friable and special considerations to crushing and grinding of the ore are necessary to avoid an excessive production of fines The Mineral Jig is an important feature of this flowsheet to recover the coarse free tin mineral as soon as liberated

The primary ore of Tin this mineral is found in hydrothermal veins and pegmatites associated with granite intrusions Because of its durability it is also frequently found concentrated in alluvial placer deposits sometimes in large enough quantities to be commercially exploitable as in Malaysia for example

By far the most important tin mineral is cassiterite (SnO 2) which has a high specific gravity of 6 99 and is therefore commonly concentrated by gravity separation methods A little tin is recovered from complex sulfides such as stannite cylindrite franckeite canfieldite and teallite

Cassiterite has been an important ore of tin for eons and is still the greatest source of tin today Most sources of cassiterite today are not primary deposts but alluvial deposits containing weathered grains The best source of original-formation cassiterite is at the tin mines of Bolivia where it is found in hydrothermal veins

Galena (PbS) and zinc blende (ZnS) are sulphide ores Cassiterite SnO2 (oxide ore) and Magnetite Fe3O4 (oxide ore) are not sulphide ore The froth flotation process is used to concentrate sulphide ores based on preferential wetting properties with frosting agent and water Hence option A and D are correct

How is cassiterite concentrated - Applications: The processing of crushed material collected gravel and refined sand etc For the areas with high environmental protection requirements as a production line containing sand washing machine can effectively reduce noise and dust pollution

Originally developed in Cornwall England to recover fine cassiterite which was irrecoverable by other means (Burt and Otley 1974) this device consists of a suspended assembly of 40 fiberglass decks arranged in two sandwiches of 20 (Figure 3 3) Each deck is 1 2 m wide by 1 5 m long separated by a 13 mm space that defines the pulp channel
