In ancient times, in extracting antimony from sulfide ore by the addition of iron, a starlike fern shaped crystalline pattern appeared during the course of solidifiion. This was dubbed the "Philosopher''s Signet Star" in 1610 and until recently the shape of these stars had commonly served to indie the grade of the metallic antimony.
antimony ores. Included are descriptions and results of smallscale continuous flotation tests and of fluidizedbed roasting tests conducted on cinnabarstibnite concentrate and on antimonyfree cinnabar products. Only the mercuryrecovery phase of the problem has been investigated. Results of studies to determine an economic
We proposed a comprehensive procedure for the separation and recovery of antimony from the AsAuSb ore. In this process, antimony was recovered in a single step in the form of hode antimony (> 98%), thereby resolving the technical problem of antimony and arsenic separation and hence, preventing the contamination of plenty of arsenic soda

In volatilization roasting, the sulfide ore or concentrate is mixed with charcoal or coke and heated in one of various kinds of roasters or shaft furnaces. The volatilized antimony oxides are recovered in some combination of bag houses, condenser pipes, flues, or precipitators.
For some time, China has been the largest producer of antimony and its compounds. The industrial methods to produce antimony are roasting and subsequent carbothermal reduction or direct reduction of stibnite with iron. The extraction of antimony from ores depends on the quality of the ore and
Roasting is a process of heating of sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.

METALLURGY. LIQUATION: Liquation is the melting of stibnite into "crudum" or "needle antimony". It is carried out between 550 and 600 degrees C. If the temperature is lower, the recovery is poor. If the temperature is any higher, the stibnite volatilizes into oxide. This method is used to upgrade lowgrade ores.

The difficulty of roasting arsenical and antimonial ores may be avoided by taking ore, 1 A.T. red lead, 1,000 grains sodium carbonate, 500 grains potassium ferrocyanide, 550 grains, with a cover of salt or borax. The button is scorified, together with the matte formed, before cupellation. E. A. Smith found this method unsatisfactory and recommends the oxidation of sulphide of antimony by

In roasting, charge material of copper concentrate mixed with a siliceous flux (often a lowgrade copper ore) is heated in air to about 650°C (1200°F), eliminating 20 to 50 percent of the sulfur as sulfur dioxide (SO2). Portions of impurities such as antimony, arsenic, and lead are driven off, and some iron is converted to iron oxide.
The concentrated (enriched) ore can contain up to 35% copper and a number of impurities such as antimony, arsenic, and lead. Roasting : reduces impurities in the copper ore and produces calcine (a mixture of products) * Concentrated (enriched) ore is heated to between 500 o C and 700 o C in air.
Heteronuclear Compounds of Arsenic and Antimony. During the roasting of copper ores when both arsenic and antimony sulfides are present, the evolution of arsenic is retarded and the volatilization of antimony increased primarily because of the formation of heteronuclear compounds.
