A small scale, portable method for extracting

To date, methods for extracting microplastics from marine sediments have been disadvantaged by complexity, expense, low extraction efficiencies and incompatibility with very fine sediments. Here we present a new, portable method to separate microplastics from sediments of differing types, using the principle of density floatation.

Surface dissolution assisted mineral flotation A review

One of the upgrading methods for zircon is flotation. Surface properties of zircon determine its flotation behavior . Surface dissolution of zircon (type E) using various cold acid solutions such as HCl (type F), HNO 3 (type G) and HF (type H) showed the interesting results (Fig. 35a, b). The results revealed that the effect of HF led to the modification of zircon, while the other dissolution agents just cleaned the zircon
