The following are just some of the minerals that can be identified in the infrared range used by the SpecCam.
Identification of minerals and their polymorphs - .
• clays - illites, smetctites
• sulphates - alunite; jarosites
• borates
• serpentine group - lizardite, crysotile
• micas - paragonite, phengite, muscovite
• kaolin group - kaolin, dickite, halloysite
• chlorite-epidote group
• carbonates - dolomites, calcite, siderite
• others - pyrophyllite, beryl, topaz, tourmaline
Identification of mineral assemblages -
• advanced argillic
• phyllic
• argillic.
Clay crystallinity
• in the kaolin, mica and illite groups
Identification of swelling clays
• discriminate high and low water content smectites
Identification of asbestiform minerals
• identification of serpentines and amphiboles
Mineral abundance and ratios
• clay fractions
• Fe:Mg ratio of chlorites
• % abundance of types of phenocrysts and xenocrysts in kimberlite, breccias and conglomerates
Grade control
• high and low grade talc
• identification of mill feed contaminants
