Fine Gold Recovery. Separating Placer Gold Particles
It uses a simple design of circulating water (much like a flushing toilet) to separate any lighter material and black sands while keeping the gold at the bottom of the bowl. Other popular equipment include spiral panning wheels, which use a specially designed spiral motion at an exact angle to capture the fine gold.

Borax melts to form a colourless transparent glass ...
Borax melts to form a colourless transparent glass, consisting of a mixture of sodium metaborate and boric anhydride (Equation 1). The boric anhydride then reacts with the metal oxide (e.g. zinc oxide) to form the metal borate (Equation 2). Na 2 B 4 O 7 Na 2 B 2 O 4 + B 2 O 3 1 ZnO + B 2 O 3 ZnB 2 O 4 2 Na 2 CO 3 + Na 2 SiO 3 NaSiO 4 + CO 2 3 10 KNO 3 + 4 FeS 2 4 FeO + 5 K 2 SO 4 + 3 SO 2 + 5 ...
