1. Effect of inorganic and organic depressants on the cationic flotation and surface charge of rhodonite-rhodochrosite
Abstract Silicates (rhodonite, tephroite, spessartine) and the carbonate (rhodochrosite) of manganese are of economic interest in silicate-carbonated manganese ores. The recovery of both mineral classes by flotation constitutes a challenge; rhodochrosite is a slightly soluble mineral that can release Mn2+ ions in pulp. In this work, the effects of inorganic

2. Propriedades de termoluminescência, ressonância paramagnética eletrônica e absorção óptica da rodonita natural e sintética / Thermoluminescence, electron paramagnetic resonance and optical absorption properties of natural and synthetic Rodonita
The optical absorption, electron paramagnetic resonance and thermoluminescence properties of natural silicate mineral, rhodonite with chemical formula (Mn,Ca,Fe,Mg)SiO3 as well as synthetic samples pure or doped have been investigated. Synthetic samples were obtained heating appropriated mixture of oxides components of rhodonite to above melting temperature
