Beryllium Extraction Process Flowsheet. Flotation offers the best means for recovering beryl in concentrate form. Much of the flotation technique developed in separation of feldspar from quartz and mica is applicable. In general, beryl will concentrate with the feldspar flotation product.

1. Introduction. K-feldspar is a typical insoluble potassium resource with large reserves and wide distribution. Because there are few sources of soluble potassium in natural resources, extracting potassium from K-feldspar has become a strategic demand in the industry (Su et al., 2015, Ciceri et al., 2017).The K-feldspar is also served as a …

The extraction of potassium from feldspar was best fitted by the Ginstling and Brounshtein kinetic model. The activation energy of 238.6 KJ/mole and 28.73 KJ/mole for low and high-temperature regions indicated that the overall extraction process follows two-steps reaction path.

The common feldspar mining processes include hand sorting, desliming, magnetic separation, gravity separation, flotation and combined process, which can separate quartz, iron, mica and other minerals. 1.
