Sommaire: The paper discusses the accuracy of magnetic inspections of corroded hoist ropes. It quantifies the error of measured LMA (loss of metallic area) caused by presence in the rope of ferromagnetic products of corrosion. The paper concludes that in mining practice this error is not significant.

Sommaire: Commercial HCl-leaching of magnesite and serpentine yields highly concentrated aqueous solutions containing 25 mass % to 33 mass % MgCl2. The partial molar enthalpies and heat capacities, the ionic activities of Mg2+ and ClÐ, and the Raoultian activity of H2O have been assessed for the concentrated MgCl2-H2O solutions at temperatures of 348 to 373 K. These thermodynamic data are used to calculate the pH of aqueous MgCl2 solutions saturated with a Mg-bearing mineral such as magnesite,...
