Abstract The purpose of the work was to analyze first stage UE “Dekhkanabad plant potassium fertilizers” find out reasons for decrease in efficiency process desliming sylvinite ore Tyubegatan deposit. It has been established that is due a content chloride and an increase insoluble residue ore, proportion weakly sludge carbonate sulfate minerals residue, compared with silicate minerals, differen...

We measured the emf of a sodium ion-selective electrode in NaCl-NaHCO3 solutions (160 mmol of Na+, 160-120 mmol of Cl-, and 0-40 mmol HCO3- per liter) with a home-built cell in steady-state after 10 min and with two commercial direct potentiometric analyzers about 20 s after the sample was introduced. Substitution of HCO3- for Cl- resulted in a small decrease in emf. We calculated the effect of...

Introduction: Carbonate minerals observed in primitive meteorites are products of either terrestrial weathering or aqueous alteration in the early solar system. Most of the carbonate minerals in carbonaceous chondrites occur primarily as isolated grains in matrix, as crosscutting veins, or as replacement minerals in chondrules [e.g., 1, 2]. A few calcium-aluminum-rich inclusions (CAIs) have bee...

Abstract Most of the world's Zn and Pb is extracted from sediment-hosted Zn-Pb deposits. The deposits hosted in carbonate rocks are hypothesized to form by mixing acidic metal-bearing brines with reduced sulfur-bearing fluids while dissolving sedimentary carbonate. To test role this process, we conducted hydrothermal experiments simulating ore formation reacting ± Ba–bearing H2S SO42– produced ...

Membrane based treatment processes are very effective in removing salt from wastewater, but are hindered by calcium scale deposit formation. This study investigates the feasibility of removing calcium from treated sewage wastewater using accelerated seeded precipitation. The rate of calcium removal was measured during bench scale batch mode seeded precipitation experiments at pH 9.5 using vario...
