Weakly magnetic iron ore is divided into hematite ore, siderite ore, limonite ore, and specularite ore according to the type of minerals. And according to the coarseness of the embedding particle size, weakly magnetic ore can be divided into coarse-grained type, medium-grained embedding type, and fine-grained, micro-fine-grained embedding type.
The classic solid phase extraction (SPE) requires a manual filtration step, consumption of organic solvents, a long extraction time, large solvent volumes and a need for extra equipment. The dispersive solid phase micro-extraction (d-SPμE) is an innovative method. It is based on dispersion in solution of micro/nanosorbents.
