9th International Symposium on Lead and Zinc Processing

A secondary zinc smelter is defined as any plant or factory in which zinc-bearing scrap or zincbearing materials, other than zinc-bearing concentrates (ores) derived from a mining operation, are processed (Barbour et al., 1978). eea.europa.eu/.../2-c-6-zinc-production . 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 ...

Zinc smelting Zinc Mining 80% of zinc mines are underground, 8% are of the open pit type and the remainder is a combination of both. However, in terms of production volume, open pit mines account for as much as 15%, underground mines produce 64% and 21% of mine production comes from the combined underground and open pit mining. Most zinc is used in the galvanizing steel process. Other uses include the automotive, construction, electrical, and machinery industries. Zinc compounds include agricultural chemicals, paints, pharmaceuticals, and rubber. Refining. Zinc concentration is usually done at the mine site, prior to reaching the zinc processing plant (refinery).

Nov 10, 2019 Abstract. China is the largest producer of lead and zinc concentrate in the world. The lead-zinc mines of China are used to produce multiple products simultaneously. To evaluate the specific environmental impact of the lead-zinc ore mining and beneficiation, life cycle assessment (LCA) was performed by SimaPro 8.5.2 software in this paper. Lead and Zinc Smelting. 333. Secondary Lead Processing. The secondary production of lead begins with the recovery of old scrap from worn-out, damaged, or obsolete products and with new scrap. The chief source of old scrap is lead-acid batteries other sources include cable coverings, pipe, sheet, and other lead-bearing metals. Solder, a tin-based

6.1 Process Overview 6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist. Zinc ore occurs in two types of deposit as primary zinc ore in thin veins known as rakes, or a secondary deposit formed by weathering of the primary mineral veins. Zinc ore is most commonly found as zinc carbonate (ZnCO 3), known as calamine or smithsonite. It generally occurs as rounded, crystalline crusts or granular, honeycombed masses that ...
