The phrase "ash extraction" is correct and usable in written English.
It can be used in contexts related to processes that involve removing ash, such as in industrial or environmental discussions.
Example: "The ash extraction process is crucial for maintaining the efficiency of the power plant."
Alternatives: "ash removal" or "ash collection".
News surfaced in July of plans to build a soda-ash extraction and processing plant on the shores of Lake Natron in Tanzania, which was the breeding site for 75% of the global population of lesser flamingos (Phoenicopterus minor).
Digestion with sc-CO2 and chemical leaching using HClaq of untreated and thermally treated ash provided high extraction for the metals Al, Ca, Fe, Mg, with the highest values achieved for thermally treated ash.
The analysis of the solid fiber fraction included ash content determination, water extraction, ethanol extraction and strong acid hydrolysis for structural carbohydrates and lignin.
A new procedure for Co determination in a complex matrix (coal fly ash) by slurry extraction-electrothermal atomic absorption spectrometry (ETAAS) is presented.
The analysis of the solid fiber fraction included ash content determination, water extraction (only on grass and grass silage), ethanol extraction, and strong acid hydrolysis for structural carbohydrates and lignin.
Trucks supply vegetables, building materials, motor fuel, and sundry goods to the farthest settlements and deliver raw materials such as petroleum, soda ash, and coal from extraction sites to nearby towns.
Proximate analyses including moisture (gravimetric method), ash (gravimetric method), fat (Soxhlet extraction method), and protein (Kjeldahl method) contents in accordance with the standard methods (Association of Official Analytical Chemist AOAC 2006), while carbohydrate contents were analyzed using the phenol-H2SO4 method (Dubois et al. 1956).
Protein was calculated as the difference between post-fat extraction weight and ash content.
Mutagenicity of coal fly ash was not detectable after extraction with a concentration of HCl known to remove nonmatrix trace elements.
This entailed moisture analysis by oven-drying at 110°C to constant weight, crude protein analysis by the Kjeldahl method, crude lipid analysis by the Soxhlet extraction method, and ash content analysis by combustion in Muffle furnace at 550°C for 4 h.
