2021-3-5 1. Introduction. Iron is the main metal in modern industry, and the main material for producing iron is iron ore. At present, the world's iron ore reserves are approximately 150 billion tons, and iron one rich countries include Brazil (16 billion tons), Russia (25 billion tons), and Australia (16 billion tons) .In the first selection stage of iron ore, the ore classification accuracy plays a ...

2020-6-1 1. Introduction. Primary halo zonation was originally defined by Safronov (1936) for prospecting deep blind orebodies and predicting resource potentials (Carranza, 2012; Li et al., 2016b).Primary halos are zones surrounding metalliferous deposits and ore bodies, created by the interactions between ore-forming fluids and enclosing rocks, where several chemical elements are introduced and ...
