"Metallurgy of Gold: Problem
Required, description of processes and machinery used in Extraction of Gold (and Silver) from earthy or siliceous ores as found in California
Ores represented by following:--SiO₂ 91.44; S(Zn,Pb)-Cu₂S 1.38; Al₂O₃, FeO &c 6.39; Au .0017, Ag₂S .12, variable in 1st and 2nd class ores
1⁰--The methods &c. employed in treating 1⁰ class ore (i.e. such as exceed in value $150 per ton)
2⁰--The methods &c. in treating 2⁰ class ore, such as contain less than $150 per ton.
Give in detail the chemistry of each process described; also illustrated by drawings of machinery for crushing, separating, retorting, melting, casting &c. including the separation of the gold from the silver.
Give as nearly as possible the commercial value of all products and by-products"--page 2
