Green Technology‐Based Utilization of Refractory Siderite
2021-5-11 Siderite ore is a typical and widely available refractory iron ore. In consideration of the growing demand for iron ores and the increasing pressure to reduce emissions in the steel industry, a green technology-based utilization of siderite ore as an electric arc furnace (EAF) burden by applying carburization roasting and magnetic separation processes is proposed.

Carburization Behavior of Siderite Pellets in CO–CO2–H2
2018-11-20 Siderite is a complex and refractory iron ore, which is hard to be utilized in iron and steel industry nowadays. For the effective utilization of siderite, a study of the carburization behavior of siderite pellet is carried out to improve the preparation of iron carbide from siderite.

Abstract To separate siderite from carbonate-bearing iron ore efficiently, specific adsorption configurations and effective species were investigated to compare the adsorption differences of sodium oleate (NaOL) on siderite and hematite surfaces. The species were analysed in neutral conditions, under which the direct flotation of siderite from hematite and quartz was carried out.

Mineral quantification at deposit scale using drill-core
1 天前 Quantification of minerals occurring within the ore are of particular benefit to mineral industry. In Elvira a compositional trend can be observed within carbonates with ankerite predominance in veins outside the mineralized system and siderite predominance in veins formed within polymetallic lens, generating a siderite-rich massive sulphide.

Upgrading nickel in laterite ores by flotation ScienceDirect
2018-6-1 In this study, upgrading nickel by flotation in three laterite ore samples, limonite, saprolite and intermediate, from different geology zones, was investigated. It was possible to upgrade the nickel grade in the saprolite sample by about 40% at more about 70% recovery using a hydroxamate collector at pH 10.

Siderite is present at the base of the cemented oolitic ironstone in a chamosite-siderite (or lepidocrocite-siderite) cement with sphalerite (Figures 6d and 6e) and rarely with barite crystals (Figures 6b and 6f). Siderite is the main cement that occupies intergranular spaces at the top of the Paleocene ironstone and Eocene gritstone.
