During the 1950s the 'classical' techniques evolved into 'rapid' schemes of analysis. These still relied on detailed solution chemistry but made use of flame photometry, spectrophotometry and complexometric titrations to eliminate some of the more time-consuming chemical manipulations.
By exploring the data analysis methods, this review can be a reference in determining which data analysis methods shall be implemented in various cases of mineral characterization using µCT systems. The primary sources of studies for this review are those that apply laboratory µCT systems in characterizing ore samples.
2.2.3. Quantitative Analysis. Quantitative analysis is performed to obtain the contents of clay minerals either in the bulk rock or in the clay fraction. XRD is the most commonly used technique, but IR spectroscopy and major element analysis, combined with qualitative XRD, have also been applied.
Selective chemical dissolution (SCD) is a commonly employed means to use a range of chemical reagents to selectively extract mineral components from soils or sediments for the purposes of quantifying, separating, concentrating, or pre-cleaning of materials for analysis.
A few elementary methods of qualitative analysis will be considered here. Minerals are, in general, insoluble in water and many of them are insoluble in acids. Their examination by the "wet" methods of chemical analysis usually require a preliminary fusion and solution to obtain solutions that can be used for the normal "wet-way" analysis.

Mineral structure analysis is a mineral analysis method that uses the diffraction effect of crystals on high-energy electromagnetic radiation to study the crystal structure of minerals (e.g., cell parameters, space group, and position of atoms in the crystal cell). Depending on the incident sources and excitation processes, it can be …
This chapter focuses mainly on the basic principles and methods of X-ray absorption near edge structure and extended X-ray absorption fine structure spectroscopy of soils, minerals, and mineral-associated (e.g., adsorbed or coprecipitated) chemical species. It focuses on sample preparation, data collection, and data analysis.
The most common instrumental methods for elemental analysis of solutions are atomic absorption spectrometry (AAS) and atomic emission spectrometry (AES). This chapter is concerned primarily with procedures for the decomposition and dissolution of samples, and the principles and applications of the two instrumental methods, AAS and …
to measure salt content. Other traditional methods of mineral analysis include gravimetric titration (i.e., insoluble forms of minerals are precipitated, rinse, dried, and weighed) and redox reactions (i.e., mineral is part of an oxidation-reduction reaction, and product is quantitated). However, these latter two methods
X-ray diffraction (XRD) analysis, as one of the most powerful methods, has been widely used to identify and quantify minerals in earth science. How to improve the precision of mineral quantitative analysis is still a hot topic. To date, several quantitative methods have been proposed for different purposes and accompanied by diverse software. In this …

The development of automated methods for the digestion of rocks and minerals without human participation (Robotic Stations) must continue. This will facilitate and accelerate one of the most time-consuming steps of the whole geochemical analysis process (from a solid sample to a sample solution form to instrumental analysis).

Abstract. Proximate analysis is defined by H. Bennett in the Concise Chemical and Technical Dictionary as the "determination of a group of closely related components together, e. g. total protein, fat.". It conventionally includes determinations of the amount of water, protein, fat (ether extract), ash and fiber, with nitrogen-free extract ...
