As seen from Table 4, lead flotation results improved slightly as a concentrate of 6.24% Pb was obtained with 40.55% recovery. However, unlike to lead flotation, the grade and recovery of zinc concentrates reduced slightly. As can be seen, the Pb and Zn grades of the tailings were high and varied between 4.03–4.79% Pb and …

In order to investigate the effect of particle size on the flotation performance in the separation of copper-gold-lead, froth products of various size fractions were collected as a function of flotation time. The optimum dosage of potassium dichromate (K 2 Cr 2 O 7) and sodium diethyldithiocarbamate (DDTC) were determined …
Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.
The averages of maximum copper grade obtained in all tests were considered (Table 3).The effect of pulp density was −0,09 for a variation of 5%; This observation (also shown in Fig. 2 a) indicates that reducing the pulp density lead to an increase in the copper grade in the concentrate. This is similar to what has been …
Sodium sulfide is one of the most widely used alkali metal sulfides in the flotation of copper, lead, and zinc minerals in their oxidized form. The sulfidization process, developed in the U.S.A. in 1915-20 for oxide copper minerals flotation, is especially suitable for oxidized lead ores in which the gangue is usually basic.
