Silica produced from HCl has a high surface area of 350 m 2 /g, whereas citric acid has a low surface area of 270 m 2 /g (Liou and Yang 2011). This could be due to the formation of sodium salts of different sizes, which can be embedded in the gel matrix and not washed away, blocking the pores and preventing accessibility of the probe molecule ...

Information on acid concentrations, temperature, type of acid, batch versus continuous process would be very helpful. ... You will need to wash the leached product which open another can of worms due to process water ...
The removal of iron from silica sand with oxalic acid has been studied under various experimental conditions in order to optimise the process parameters and reach a high degree of iron removal at minimum operating cost. The parameters studied were: temperature, pH of the solution, oxalate concentration, Ar purging, and ferrous ions addition to ...
Occasionally an acid wash on perforations is undertaken to reduce formation skin damage. The acid is circulated to the bottom and the area to be treated allowed to soak. To aid clean up, the acid may need to be nitrified, or nitrogen gas lift may be required. • Acid squeezing requires the injection of acid into the formation via the perforations.
Silica sand consists of fine pieces of quartz and other minerals such as salt, silt, clay, dust and various powders. Washed sand goes through a cleaning or "washing" process that removes these additional substances. MS Industries is a provider of naturally occurring smaller sized silica sand with microproppants and proppants. Our sand is ...
Notes: (1) The Fe 2 O 3 % is the chemical analysis result from treated sample. (2) The data in bracket is the result of continuously replacing water. α – the iron content in sample; γ – the iron content after acid treatment, that is the limit value of iron elimination; β 1, β 2 – the iron contents after ultrasonic wash and mechanical scrubbing respectively; E 1, E 2 – the ...
Add the sand to the boiling water and let it simmer for a few minutes. This process helps dissolve the salt particles present in the sand. After boiling, carefully pour the water and sand mixture through a coffee filter to separate the sand from the water and salt solution. The coffee filter will capture the salt, ensuring that only clean sand ...

The most abundant alternative to mined crystalline silica sand is what nature has provided plenty of by oceans and rivers. Beach and riverbed sand is naturally low in dust and hardly gives off any residue when touched. This is because even though the sand is composed of crystalline silica it does not contain the dangerous dust.
