The second method of refining gold involves the use of chemicals. Strong acids are used to dissolve the impurities in the gold ore and afterwards, are neutralized and washed away, taking the impurities with them. The resulting product is a muddy substance that is almost pure gold (99.999% or 24K).

Filtration. Filtration is a separation method used to separate out pure substances in mixtures comprised of particles, some of which are large enough in size to be captured with a porous material. Particle size can vary considerably, given the type of mixture.For instance, stream water is a mixture that contains naturally occurring biological organisms like bacteria, viruses, and protozoans.
