Lead, Zinc Ore from Nigeria
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 (ZnCO3), known as calamine or smithsonite. It generally occurs as rounded, crystalline crusts or granular, honeycombed masses that have a vitreous or pearly luster and are typically dirty brown or grey in colour. Locally it was known as â??dry boneâ?? ore, having a cellular to spongy appearance reminiscent of dry bone. Calamine is actually a secondary mineral, found principally in the oxidized zone of the zinc-bearing ore deposits. It is derived from the alteration of the primary zinc sulphide (ZnS) mineral sphalerite. This is generally a dark grey or black, highly lustrous mineral, but can vary in appearance. Both occur on Mendip. Its chief use was to make brass by mixing with copper.
Rotary tilting refining furnace The rotary tilting refining furnace is mainly used for the pyrometallurgical refining of recycled metals (mostly used for impure copper). In order to improve the technical and economic comprehensive indicators of the tilting refining furnace, it is best to have a copper grade higher than 90% when entering the furnace. For raw materials with lower copper grades, it is best to first undergo pre-treatment in the blast furnace and blowing furnace before entering the tilting furnace. The furnace body of the rotary furnace is installed on a rotating frame, which, under the action of a hydraulic cylinder, can tilt the furnace body within a certain angle range to achieve process actions such as feeding, melting, and dumping slag. At the same time, the furnace body can rotate around its axis under the action of the transmission mechanism; The rotary motion improves the heating efficiency of the furnace and is of great significance for the overheating of the molten metal. When melting metal in this furnace, a certain amount of slag forming agent needs to be added. The molten slag forming agent and slag liquid have a protective effect on solid and liquid metals, which can prevent metal oxidation The burning loss rate of elements such as silicon and manganese in a rotary cupola is equivalent to that of a coke burning cupola. The content of carbon elements in the rotary furnace is decreasing, so it is necessary to add a certain amount of carburizing agent ( graphite) to the furnace material.
Lead slag produced from rotary furnace lead percentage is 20 to 25%
