Dear Colleagues, Physical separation is one the main methods of recovering valuable minerals from an ore (in addition to flotation and hydrometallurgy).Physical separation includes gravity concentration, classification techniques such as hydrocyclones and air classifiers, solid–liquid separation (e.g., thickeners and clarifiers), magnetic separation, and electronic …
I've seen a lot of tips about cutting the first coat of polyurethane with mineral spirits to reduce drying time. However, given that it's the first coat, I have a full can of polyurethane. ... It seemed to clear up then. I started the job, and about 45 min in there seemed to be some phase separation going as the shallow end of the paint pain ...
The Composite is prepared by thermally induced phase separation method. The PU particles (1.5 g) were put into 50 mL of 1,4-dioxane, and then stirring at 60 °C for 3 h to gain the uniform PU solution (3 wt%) (Scheme 1).Then the above solution was cooled down to room temperature.
MG Series. Used for feed material generally containing up to 25 per cent heavy mineral (up to 40% in some applications). The company offers an extensive range of spiral separators to …
Principle of Separation. Spiral separation is based on the specific gravity difference present in a feed mineral suite. When fed a dilute pulp mixture of minerals of different specific gravities, the lighter minerals are more readily suspended by the water and attain relatively high tangential velocities so that they climb toward the outer rim of the spiral trough.

Applying the polyurethane too thickly. If you apply the polyurethane too thickly, it will not be able to dry properly and will leave brush marks. Applying the polyurethane in the wrong direction. Polyurethane should be applied with the grain of the wood. If you apply it against the grain, it will leave brush marks. Not sanding between coats.
