In flotation, a mixture of slurry (crushed ore and water) and frothing agents are added into a flotation machine. A tube releases air into the tank of the machine and an agitator creates air bubbles at the bottom of the tank. Minerals that are hydrophilic, such as gold, attach to the bubbles' surface and are brought up to the top of the tank.

Refining by amalgamation consisted essentially of grinding the ore to a coarse dust and sprinkling a small amount of mercury over it. In time (typically, several weeks) the mercury would amalgamate with the silver atoms in the ore, forming a pasty substance. From this, pure silver could be obtained by applying enough heat to volatilize the mercury.
