Structure, composition and inlay size of antimony ore decides the suitable concentration method. Gravity separation works well for most antimony ores because antimony is kind of mineral with big specific gravity and coarse inlay granules. Stibiconite, kermesite and valentinite is the antimony ore easiest to beneficiate by gravity separation.
This method is used when a higher ore contains impurities with higher density. This method is used for the concentration of Sulphide ores. (Eg: Copper pyrites, iron pyrites, Galena, Zinc blende etc.) Copper is mainly extracted from copper pyrites. After the concentration of its ore by froth flotation process, the ore is roasted in a current of air to remove arsenic, antimony and …

Assaying Antimony. To determine the amount of antimony in an ore containing sulphide of antimony and more or less vein- stuff:— Place about 2,000 or more grains of broken-up ore in a crucible, the bottom of which is perforated, and the hole in which is partially closed by a small piece of charcoal.
Pelletized antimony concentrates (obtained through crushing, grinding, gravity concentration and flotation of ores) are combined with coal and smelted in a blast furnace (at 1300 to 1400 O C) under oxidising atmosphere. Antimony oxides thus formed are volatilized and collected (in a dust collector).

Stibium Mining and its investment partners acquired the historic Consolidated Murchison gold-antimony mine in South Africa with the support of Core. Core assisted Stibium with on-site support in the recovery and retreatment of gold …
The gravity separations are simple and separate mineral particles of different specific gravity. As the density of gold mineral is much bigger than gangue mineral, for the gold mine which has gold particles people often use the gravity separation process. Gravity concentration is a proven process for mineral beneficiation.
Gravity concentration allows for reducing the number of equipment units in subsequent processing stages, lowering the gold content in tails, and increasing the overall …
A flotation-gravity concentration-reflotation process for antimony oxide ore from Iran was adopted by Chen D.X. [36]. First, flotation is used to recovery antimony sulfide from the oxidized ore. Using a fractional shaker and other gravity processes these recycled crude antimony oxide particles were separated, and recovered using a flotation ...
The stibnite sometimes carries several ounces of gold to the ton. At Prince William, New Brunswick, stibnite and native antimony occur in quartz veins cutting slate and quartzite near intrusions of granite and diabase. At South Ham, Quebec, native antimony and stibnite occur in a schistose, slaty rock at its contact with serpentine and diabase.
Metallic antimony (β-phase) is the most stable form that possesses a brittle, ... In addition, the authors suggested their idea of a reprocessing flowsheet that would involve a combination of gravity concentration, grinding, and classification in a closed circuit followed by desliming, sulfidization roasting, and enhanced flotation. ...
