filtering colloidal clay from your water can be a difficult feat to achieve. the extremely fine particles can lead to cloudy well water and cannot be removed with standard filters. typical sediment filters of microns will probably not be adequate.
water treatment In one of the few studies on acid mine water treatment by means of zeolites, moreno et al. showed that zeolites synthesized from coal fly ash effectively removed heavy metals. In another study, zamzow et al. compared different zeolite types with respect to heavy metal uptake from simulated wastewater and

the clay will need to be sieved to remove unwanted material such as rocks, twigs, and roots. sieving can be done either of two ways. the clay can be pulverized when dry and then sieved, or dried, slaked down in water, then sieved. the finer the mesh used, the fewer inclusions your working clay will have. suggest using a 50-mesh screen
recovering fine gold from black sands is one of the most challenging aspects of gold mining. while we are all hoping to find that once-in-a-lifetime gold nugget, the vast majority of gold that we find as prospectors is very small in size, ranging from gold flakes down to dust so small that it is nearly invisible. extremely fine particles of gold like this can be very difficult to separate from
