2. Summary of gold Plants and Processes. The general principle behind the structure of the volume is that of flowsheeting based on unit operations and applied to a mineralogical classification of gold ore types. Typical unit operations associated with the generic process flowsheet embodied within the structure of this book are shown in Fig. 1.

Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This …

Ore processing is a 24 hour operation. Ore is stockpiled at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added to raise its pH. Following crushing through a jaw crusher, the ore is fed into the semi autogenous grinding (SAG) mill along with water and steel balls.

Two tests were made in the laboratory of which I have a note: one for 10 minutes and one for 15 minutes. The ore contained $6.50 gold and 2% copper; 12% of this sample would remain on a 60-mesh screen. The first one gave a concentrate containing $22.70, 9.4% copper, and 18% insoluble, with an extraction of 51% of the gold and …
