Valentine instructs the reader to grind antimony ore (stibnite, native antimony sulfide), roast it slowly until it turns light gray, melt this "ash" in a crucible, and the pour out the molten material to provide "a beautiful, yellow, transparent glass".

Process of smelting antimony ore

In carrying out the process, it has been found that the mineral senarmontite is the cheapest and easiest ore for roasting purposes, for the production of antimony trioxide. After the to such a temperature as will reduce: theantimonious oxide to metallic antimony.

Lead: smelting, producing and classification-Metalpedia

The majority of the deposits are mixtures of minerals, hence lead ore is usually obtained as a byproduct of other metal mining such as zinc, silver or copper. In fact, lead ore is a main source of silver and contributes substantially towards the world's total output. The most common lead ore is galena (PbS), which contains 86.6% lead.

Heating ores to elevated temperatures is called roasting, and it causes the oxygen in the air to convert the sulfur in the ore to sulfur dioxide, which is a gas and is emitted to the air. The process works best when the ore is crushed to small pieces before roasting.

Oxidizing Roast; Stibnite the Antimony Mineral

The leading antimony mineral is stibnite. In smelting stibnite ore two processes are available, precipitation and roasting-reduction. The former is suited, only for high-grade ores. As low-grade ores are more common than high-grade, roasting-reduction is of greater importance than precipitation. In the roasting process the aim may be to leave the oxidized antimony in the ore, or it may be to ...

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 low-grade ores.

Mineral Commodity Profiles: Antimony

Domestic production of antimony as a principal mine product (that is, from antimony ores) was as high as 5,000 t in 1943; in 1948, it peaked at about 5,900 t. Most of the production in those years came from the Yellow Pine Mine, in Idaho. After the early 1950s, production as a principal product dropped well below 1,000 metric tons per year (t/yr).
