sulfuric acid slag lead zinc flotation cells

Shown in Fig. 1. Thetailingof cerrusite flotation is the zinc concentrate containing 20 25 Zn, which is leached by sulfuric acid to extraction the zinc metal (Irannajad 2007 Mehdilo et al, 2010 Ejtemaei and Irannajad, 2008). In recent years by decreas ing the Zn content of the ore, upgrading oftailingby froth flotation before acid leach.

The overflow from thelead scavenger cellsis fed to the zinc conditioner. Various reagents are added for specific purpose. These are sodium cyanide for pyrite depression, copper sulfate as sphalerite activator, Sodium Isopropyl Xanthate as collector and MIBC as frother.Zinc flotationis achieved in two stages of rougher and scavenger cells.

Zincprocessing -Zincprocessing-Ores:Zincores are widely distributed throughout the world, although more than 40 percent of the world’s output originates in North America and Australia. The commonzinc-containing minerals are thezincsulfide known aszincblende or sphalerite (ZnS), a ferrous form ofzincblende known as marmatite [(ZnFe)S], and azinccarbonate known as calamine or ...

Manypartial oxidationreactor systems include a quench chamber. Whenslagis removed from thepartial oxidation reactor,volatile metals such aslead, zinc, and cadmium condense and solidify in the quench chamber water in the form of finely divided particles having a particle size on the order of about 1×10 8 meters to 5×10 6 meters.

The calcine was subjected tosulfuric acid leachingfor separation of copper,lead, andzinc;i.e., copper andzincwereleached, andleadwas retained in the residue. The optimum parameters of theleachingprocess were: aleachingtemperature of 55 °C;sulfuric acidadded at 828 kg/t calcine; a liquid:solid ratio of 3:1; and aleachingtime of 1.5 h.

The flotation concentrate contained 7.79% Cu, 22.00% Pb, 4.81% Zn, 8.24% S, and 12.15% CaO;copper sulfideaccounted for 76.97% of thecopper, lead sulfidefor 25.55% of the lead, andzincsulfide...

The sulfuric acid leach dissolves majority of the zinc, leaving 5-10% in the residue, along with the impurities of gold,lead,and silver. This residue is melted to form a slag and powdered coal or coke is blown into the melt along with air, a process known as slag fuming.Zincis reduced and vaporized from the slag; theleadis converted to its metallic form and dissolves the silver and gold.

Zincsmelting is the process of convertingzincconcentrates (ores that containzinc) into purezinc. The most commonzincconcentrate processed iszincsulfide, which is obtained by concentrating sphalerite using the frothflotationmethod.There are two methods of smeltingzinc: the pyrometallurgical process and the hydrometallurgical process (over 90% of hydrometallurgical process is in ...
