Introduction To Gemology | Igneous Rock | Rock (Geology)
Gray is a modifier of saturation, not of tone. Saturation Saturation is the brightness (or purity, intensity) of a hue. The purer the hue, the higher grade it will get on the saturation scale. The saturation scale goes from 1 to 6. Lower grades (1 to 3) can have a gray or brown modifier, while in grades above 3 these modifiers are absent.

FROTH FLOTATION | Wetting | Chemical Compounds
FLOTATION is a physico-chemical separation process that utilizes the difference in the surface properties of the valuable and gangue minerals. FROTH FLOTATION involves three different phases- solid (fine ore powder), liquid (water) and froth. The process of separation of mineral includes three important mechanisms : 1.

Froth flotation of fluorite: A review - ScienceDirect
Fluorite (CaF 2), mainly composed of calcium fluoride, has a cubic crystal structure with a space group of Fm-3 m, having a = b = c = 0.5463 nm and α = β = γ = 90° [], as shown in Fig. 3.The calcium atoms are eightfold coordinated to eight surrounding fluorine atoms at a distance of 0.237 nm. Conversely, the fluorine atoms are surrounded by four calcium atoms, forming ideal tetrahedrons.

As a common depressant, acidified water glass (AWG) has strong inhibitory effects on fluorite and calcite. The inhibited fluorite is difficult to be recovered, thus resulting in the waste of resources and low flotation efficiency. In this study, the interaction of fluoride ions with fluorite and calcite surfaces was investigated, and its effects of AWG adsorption on mineral surfaces were ...
