Fatigue properties and damage constitutive model of salt rock based on CT scanning

International Journal of Mining Science and Technology
To investigate the macroscopic fatigue properties and the mesoscopic pore evolution characteristics of salt rock under cyclic loading, fatigue tests under different upper-limit stresses were carried out on salt rock, and the mesoscopic pore structures of

Enhanced Superconductivity in Rock-Salt TiO. [PDF]

ACS Omega, 2017
Oxygen stoichiometry is critical for physical properties, but it is hard to precisely control in many multivalent transition metal oxides, for example, cuprate superconductors, magnetoresistive manganite oxides, and TiO x (x < 2). We have developed a new method to synthesize rock-salt TiO in a sealed and evacuated quartz tube by using KClO4 as the only

Simulation of rock salt dissolution and its impact on land subsidence [PDF]

, 2014
Extensive land subsidence can occur due to subsurface dissolution of evaporites such as halite and gypsum. This paper explores techniques to simulate the salt dissolution forming an intrastratal karst, which is embedded in a sequence of carbonates, marls,

Recycling of Rock-Salt Dust and Brine after Rock-Salt Production

Inżynieria Mineralna, 2016
This paper concerns the issue of the management and recycling of rock-waste (rock-salt dust in particular), tailings, and brine gener - ated by rock-salt extraction and processing. The author discusses the methods of brine treatment for the needs of further processing. In that context, an option for combined rock-salt dust and salt-mine brine recycling
