Zinc Ore - an overview ScienceDirect Topics

Zinc is produced from ore mining, mineral processing, concentration, roasting, leaching, purification and electrolysis. Table 14 describes the major findings and recommendations from the research conducted related to LCA of this metal. Genderen et al. analysed the cradle-to-gate LCA of zinc concentrate and special high-grade zinc.

Zinc: smelting, producing and classification-Metalpedia

Zinc ores contain 5-15% zinc. To concentrate the ore, it is first crushed and then ground to enable optimal separation from the other minerals. Typically, a zinc concentrate contains about 55% of zinc with some copper, lead and iron. Zinc concentration is usually done at the mine site to keep transport costs to smelters as low as possible.
