The sample of oxide inclusion was obtained in the different stage of steelmaking for the 65 steel. The microstructure was observed by using scanning electron microscopy (SEM) to analyze the composition and type of inclusions. It was shown that the microscopic inclusions in the high carbon steel were mainly massive and cluster Al2O3, spherical and slope silicate inclusion, calcium-aluminates inclusions and sulphide complex inclusions. The measures including raw material requirement, improving of the converter, LF refining and continuous casting operations were put forward to decrease inclusion.

Typical features of platinum group minerals (PGMs) and the results of 190Pt–4He dating of the Fe–Pt solid solutions are presented for complex gold–platinum–diamond placers with unidentified sources of the Anabar River basin. For the first time, the 190Pt–4He isotopic system is used for determination of the possible age of the primary source of a PGM placer from the example of ferroan platinum with a disordered structure along with isoferro- platinum. The PGMs of these placers mostly include ferroan platinum and isoferroplatinum and rare Ru–Ir–Os alloys. The calculated bulk composition of the silicate inclusion of Ir platinum corresponds to the rocks of the ijolite–melteigite series. The 190Pt–4He age of the Fe–Pt solid solution grains is 261 ± 13 Ma. Thus, our data indicate the relation between placer PGMs of the Anabar River basin and Permian-Triassic complexes of alkaline-ultramafic rocks.
