Zinc: smelting, producing and classificationMetalpedia
Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphalerite using the froth flotation methodThere are two methods of smelting zinc: the pyrometallurgical process and the hydrometallurgical process (over 90% of mineral extraction and processing of minerals in the Lao PDR, except for gas and natural oil which will be governed by separate regulations Chapter 2 Basic Geological Survey and Preservation of Mineral Resources Article 8 Basic Geological Survey Basic geological survey refers to the initial gathering of information on mineral outcrops and geological structures for LAO PEOPLE’S DEMOCRATIC REPUBLIC Vientiane TimesExtraction of ores from the Earth’s crust The Earth’s crust contains metals and metal compounds such as gold, iron oxide and aluminium oxide; When found in the Earth, these are often mixed with other substances ; To be useful, the metals have to be extracted from their ores through processes such as electrolysis, using a blast furnace or by reacting with more reactive Extraction of Metals (1021) CIE IGCSE Chemistry
