1 Froth Flotation – Fundamental Principles
concentration. Figure 1: The flotation system includes many interrelated components, and changes in one area will produce compensating effects in other areas (Klimpel, 1995) Froth flotation is a good example of an engineering "system", in that the various important parameters are highly inter-related, as shown in Figure 1.

Common & Basic Formulas for Mineral Processing Calculations
By perfect concentration, assuming the lead to be as galena and the zinc as sphalerite: The value of crude ore by perfect concentration is then $11.46 for the lead concentrate and $11.18 for the zinc, or a total of $22.64 per ton of crude ore. By formula (28) Economic recovery = 100 x 18.50/22.64 = 81.7%

A Paradise Named Galena – Nevada Magazine
In 1860, the site near modern day Galena was purchased as a gold mining property by brothers R.S. and Andrew Hatch. Unfortunately, the ore from their mines turned out to be worthless. Though it contained gold, it also had a high concentration of a lead sulfide known as galena—a mineral that wasn't too valuable for a 19 th century prospector ...
