Siderite - Mineral Properties, Photos and Occurence

2018-11-22  Siderite is both an iron ore and gangue mineral. Its principal economic value lies in its high iron content and the absence of process contaminants such as sulfur or phosphorous. It is part of a large group of isomorphous minerals, the calcite group carbonates, which share similar physical properties, and rhombohedral crystal form.

Different Types of Iron Ore - 911metallurgist

2016-10-5  Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.

Synergic Surface Magnetization of Siderite on Hematite ...

The surface magnetization without adding any iron-containing substance as a magnetic seed is called self-magnetization. Tests show that temperature and pH of the slurry are two important factors in the self-magnetization of siderite and its synergic effect on hematite; that the self-magnetization took place on siderite but did not on hematite while a synergic effect of surface magnetization, i ...
