How do you calculate capital recovery? - WhoMadeWhat ...

The theoretical grade-recovery curve for an ore is a definition of the maximum expected recovery by flotation of a mineral or element at a given grade. This is defined by the surface area liberation of the value minerals and is consequently directly related to the grind size utilised in the process.

Mar 06, 2016  To avoid competitive adsorption, an adequate dosage of DDA (8.6 × 10 −4 M) was used for the artificial mixture flotation. Figure 7 shows the flotation recovery of magnesite and quartz in the artificial mixture. When the quartz content was 5%, the recovery of quartz was reduced dramatically (from 96.66% to 37.15%), and as the content increased, the recovery gradually increased.
