Fire and Explosion Prevention in Coal Pulverizing Systems

COAL DUST FIRES AND EXPLOSIONS The pioneering effort to establish the relative ignition sensitivity and explosibility of air and various flam- mable dust mixtures was carried out by the U.S. Bureau of Mines over 60 years ago. Mine safety, and later, the safety of coal pulverizing systems, have received much detailed attention.

Recovery of Gold by Precipitation with Zinc

Mar 17, 2017 Some zinc is no doubt precipitated as sulphide by soluble sulphides formed from the ore during the dissolving treatment, but it would seem that both these causes need to be supplemented by something further. The writer is inclined to account for it by the effect of the lime added to the pulp upon the double zinc cyanide.

Zinc cyanide Wikipedia

Zn(CN)2 is fairly easy to make by combining aqueous solutions of cyanide and zinc ions, for example via the double replacement reaction between KCN and ZnSO4: ZnSO4 + 2 KCN → Zn(CN)2 + K2SO4For commercial applications, some effort is made to avoid halide impurities by using acetate salts of zinc: Zn(CH3COO)2 + HCN → Zn(CN)2 + 2 CH3COOH
