·Differ from rock gold separation method it is relatively simple to extract gold from sand There are many simple methods like panning using a rocker box using a sluice box amalgamation and roughing with a chute or jig the coarse concentrate is usually enriched by a shaker with a very high ore ratio its recovery rate can reach
CH4 recovery in the water saturated silica sand bed was considerably low ∼% because N2 molecules might compete with CH4 molecules to enter the hydrate crystals under high pressure conditions The addition of THF to the bed of silica sand particles reduced the nucleation time of gas hydrate formed from the 30 mol % CH4/N2 gas and
·Rapid growth of the industrial and electronics sectors has led to an ever mounting demand for gold Gold mining can be highly resource intensive due to the need for selective gold separations from dilute streams in the presence of multicomponent metallic species The development of efficient gold separation technologies is critical to mitigate the
In this study adsorption as an environmental friendly technique has been applied for separation and recovery of gold Au from gold mining rock sample with iron sand magnetic material coated with silica/chitosan MMSC The works included preparation and characterization of adsorbent; gold leaching from the rock sample and adsorption desorption of Au III in leaching solution
·DNA extraction from clinical samples is commonly achieved with a silica solid phase extraction column in the presence of a chaotrope Versions of these protocols have been adapted for point of care POC diagnostic devices in miniaturized platforms but commercial kits require a high amount of input DNA Thus when the input clinical sample contains less than 1
