EXPERJMENTAL ARC-FURNACE SMELTING OF TITANIFEROUS

The test results indicate that it is possible to smelt a sand concentrate containing 53o0 pct Fe and 4.4 pct Ti02 to yield pig iron, while slagging-off the titania in the easiest and most economical manner. However, an attempt to smelt a sand concentrate to yield pig iron, plus a slag containing over 60 pct Ti02, was unsuccessful. This failure ...

Refining (metallurgy) - Wikipedia

The product of the blast furnace is pig iron, which contains 4–5% carbon and usually some silicon.To produce a forgeable product a further process was needed, usually described as fining, rather than refining.From the 16th century, this was undertaken in a finery forge.At the end of the 18th century, this began to be replaced by puddling (in a puddling furnace), which was in turn gradually ...

Zinc smelting - Wikipedia

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific ...

SMELTING SILVER

native silver, silver sulfide, iron sulfide, and iron oxyhydroxide hydrates. I guessed that the sulfides and iron minerals were not abundant enough to justify roasting, so the only thing I did to prep my ore was to wash and crush it. Quartz from the mine; bright spot near the center is native silver. Field of view is 1 cm. Furnace

Electric Smelting Furnace of Ore

The furnace is simple, low in first cost and repairs, consumes 2,300 to 3,000 kw.-hr. per ., ton of iron, and is the only electric pig-iron furnace that by using cheap reducing agents (no charcoal), utilizes the gas and permits the making of iron of any desired quality. Another advantage is that furnace units can be made larger than for other ...

Zinc processing - The zinc-lead blast furnace Britannica

The zinc-lead blast furnace. Sintered zinc and lead concentrates, mixed with metallurgical coke, are charged into the top of a shaft furnace, into which preheated air is blown through nozzles, or tuyeres, at the base (see figure).This procedure is similar to that followed in an iron blast furnace, with the important difference that the major products of reduction here are a zinc-bearing gas ...

mining technology: Iron Ore Processing for the Blast Furnace

About 16 pounds of Bentonite are added to every ton of iron ore concentrate. Small amounts of limestone (1%) are also added and mixed with the concentrate at this point. Limestone is added to meet the requirements of steel customers in the blast furnace process. The iron ore concentrate is now mixed and ready for the pelletizing process ...
