Gold flotation. Flotation process is widely used for lode gold processing. In most cases, the flotation method has a good effect in sulfide-containing gold ore with high floatability.

The quantity of borax for melting in a gold melting machine will be determined by the quantity of gold to be melted. With some borax and heat, it is possible to extract gold from a simple ore. Once the borax melts, it lowers the melting temperature of everything in the ore. Generally when melting gold, a small amount of borax is needed for melting.

They all have their own pros and cons -- and price tags.

The old timers commonly used rail and mining cars to move gold or silver ore and waste rock, and this method is still used in some smaller mines.
