Digestion Method an overview ScienceDirect Topics
The ultrasoundassisted pseudodigestion method has been developed for rapid and ultratrace detection of iron and manganese in samples of citric acid fermentation medium (beet and cane molasses and raw sugarbased media)110 Ultrasonicassisted acid digestion has been utilized for the sample preparation of total heavy metal species (Cd, Cr, Ni, and Pb) and their determination by ETAAS in different 7306020 Manganese ores and concentrates — Determination of hygroscopic moisture content in analytical samples — Gravimetric method Manganese ores — Determination of active oxygen content, expressed as manganese dioxide — Titrimetric method Manganese ores and concentrates — Determination of nickel content — Dimethylglyoxime ISO 7306020 Manganese ores The enrichment of manganese ore by fire is another dressing method for highphosphorus and highiron manganese ore which is difficult to select It is generally called the manganeserich slag method It is a high temperature beneficiation method for selectively separating manganese, phosphorus, and iron by controlling the temperature of them in The 7 Most Useful Manganese Ore Beneficiation Methods
Optimization and evaluation of the method for the
Many intensive research efforts have been made with regard to the detection method adopted in ISO 4298:1984 Early in 1946, Lingane and Karplus [ 2] proposed the method for the determination of manganese by the potentiometric titration of manganese (II) with permanganate in neutral pyrophosphate solution There is a constant demand from the mining industry for faster and more costeffective methods for the determination of various elements in ores, while maintaining quality analytical attributes, such as high recovery and method reproducibility Acid digestion techniques have long been popular in this application, since the cost of digestion is highperformance sample digestion of base metal sample digestion methods, such as acid digestion, fusion, or ashing, are required Sample digestion is thus a fundamental and critical stage in the process of sample analysis, and it is often (PDF) Sample digestion methods ResearchGate
