Magnesium and silicon recovery from chrysotile asbestos waste of the deposit Zhitikara, Kazakhstan.

Waste generated during asbestos manufacturing contains substantial quantities of iron, nickel, magnesium, and silicon. The existing techniques for processing chrysotile-asbestos waste (CAW) cannot fully recover these elements. Therefore this paper presents a hydrometallurgical method for processing the CAW of the Zhitikara deposit in the Kostanay region of Kazakhstan.

The Use of "Acellbia"-A Biosimilar of Rituximab in Systemic Sclerosis.

The possibilities of modern therapy for systemic sclerosis (SSc) remains limited, since most of the used drugs do not have a disease-modifying effect. This encourages the study of new approaches that potentially affect the fundamental pathological processes underlying the disease. One example is anti-B-cell therapy, in particular rituximab (RTX).

Safety and Tolerability of Rituximab in the Treatment of Systemic Sclerosis.

Rituximab (RTX) has been used for the treatment of systemic sclerosis (SSс) for a long time and has shown good efficacy for skin fibrosis and interstitial lung disease (ILD). However, data on tolerability and long-term adverse events (AEs) during RTX therapy in SSc are insufficient. The objective of this study was to assess the tolerability and safety of RTX in patients with SSс in a long-term prospective follow-up.

Processing of titanium-containing ores for the production of titanium products: A comprehensive review.

This article discusses the main technologies for processing titanium-containing raw materials, the advantages, and disadvantages of various technological solutions. The analysis of the literature revealed that the traditional methods for the production of titanium products are mainly focused on the use of ilmenite concentrates. In connection with the depletion of ilmenite deposits, in the near future, there will inevitably be a need for a switch to the use of complex ores - titanomagnetite.
