The mining process

Our zinc concentrates are sold in the domestic market and exported overseas, while our lead concentrate undergoes further processing and smelting on site to become crude lead, or lead bullion. Lead concentrate is mixed with high grade silica, limestone and copper slag, a by-product of our copper smelting operations. Get price

Apr 01, 2020The 47-acre horizontal retort smelter processed zinc ore from approximately 1915 to 1928. US Zinc Company, a former subsidiary of ASARCO, Inc., leased and operated zinc-smelting facilities in Kusa during the early 1920s. Investigations revealed high concentrations of lead, zinc, and arsenic in the soils. Get price

Galena Mining Conference

The ruins of early smelting furnaces have been discovered in recent years and are being preserved. As the mines deepened, the galena gave way to sphalerite (zinc sulfide). Unfortunately, until the late 1850's there was no market for the zinc and zinc minerals were discarded as waste. Initial efforts to smelt zinc near the mines were unsuccessful. Get price

Zinc

Zinc. Zinc is often found in nature together with lead in sulfide ores. The metals are separated during refining. As zinc is resistant to corrosion and easy to apply, much of it is used to protect iron and steel-based products. Uses of zinc. Zinc is used as coating to protect iron and steel from corroding in the atmosphere, water and soil. Get price

Extraction of Zinc

Zinc Mining. The most commonly available ore used in the extraction of Zinc is called Zinc Blende also known as Zinc Sulphide (ZnS). Historically extraction of zinc has been more difficult than extraction of other metals because at temperatures where metals such as iron typically begins to melt, zinc is a gas. Get price

Zinc Metallurgy Overview

2. Zinc electric arc furnace smelting takes classified sintered ore and coke as raw material to produce zinc vapor. Zinc vapor discharged from the furnace top to a zinc spray condenser to get crude zinc. This crude zinc is distillation refined to high purity zinc and valuable metal like indium, germanium, and silver. Get price

Fig.37 Zinc and tin contents for unleaded Roman alloys. The lower levels of trace elements in Roman alloys could only be achieved through the use of hotter or more oxidising smelting conditions, repeated smelting, or more rigorous fire-refining purification of the finished metal. All of these processes would tend to reduce the overall yield Get price
