After carrying out a froth flotation separation, the products are as shown in Table 1. Using this data, calculate: (a) Ratio of concentration (b) % Metal Recovery (c) % Metal Loss (d) % Weight Recovery, or % Yield (e) Enrichment Ratio Table 1: Grade/recovery performance of a hypothetical copper ore flotation …
However, today "flotation" is the principal method of mineral processing throughout the world. Capacity of the first flotation mill was only 50 tons of ore per day. Now more than 100 different minerals are commercially recovered by flotation and some mills process as much as 50,000 tons of ore every 24 hours. CHANGES IN FLOTATION MACHINE DESIGN
Flotation tests using starch were made on a quartz ore containing carbonaceous schist from the Argonaut mine, Jackson, Calif.; a talcose ore from the Idaho-Maryland mine mentioned; a talcose-clayey ore from Gold Range, Nev.; a siliceous, iron and manganese oxide ore from the Baboquivari district, Nevada; carbonaceous and aluminous slime from ...
In the flotation tests, potassium dichromate (K 2 Cr 2 O 7), sodium diethyldithiocarbamate (DDTC) and methyl isobutyl carbinol (MIBC) were separately used as the lead depressant, the copper collector and frother.All reagents for tests are analytical grade. Tap water was used for the lab flotation tests. The chemical analysis results of the tap water are shown in Table 4.

W.G. Davenport, in Encyclopedia of Materials: Science and Technology, 2001. 1.1 Physical Beneficiation. Beneficiation of copper ores is done almost exclusively by selective froth flotation. Flotation entails first attaching fine copper mineral particles to bubbles rising through an ore–water pulp and, second, collecting the copper minerals at the top of the pulp as a briefly stable mineral ...
