  • influence of Aluminum Sodium Silicate on olivine flotation with Sodium oleate
    Minerals Engineering, 2019
    Co-Authors: Shuai Fang, Kaiqian Shu, Zhoujie Wang
    Abstract:

    Abstract In this work, the performance of the novel depressant AluminumSodium Silicate (Al–Na2SiO3) was compared to that of Na2SiO3, and the flotation and adsorption on the olivine surface were investigated with single-mineral flotation tests, zeta potential measurements, microcalorimetry, Fourier-transform infrared (FTIR) spectroscopy, and thermodynamic analyses. From the mineral flotation test results, Al–Na2SiO3 was found to exhibit an improved depression capacity as compared to the samples in the absence of Al3+, and the depression properties of Al–Na2SiO3 were found to depend on the Al3+ concentration. Thus, when the Al3+ concentration was higher than or equal to 0.1 mM, a significant depression capacity for olivine could be realized. From the obtained zeta potentials, it was found that by introducing assistant Al(III) species, the zeta potential of olivine exhibited a more positive integral shift than that of pure olivine and NaOL + Na2SiO3. In addition, according to the species distribution of Al2(SO4)3 and Na2SiO3, Si(OH)4 could interact with Al(OH)2+, Al(OH)2+, and Al3+ ions to form some monomeric Silicate species and/or a polySilicateAluminum material to inhibit the floatability of olivine. Moreover, the results of microcalorimetric measurements revealed that the reaction heats of the utilized reagents could be in the order of Al3+

  • Effects of Sodium carbonate and Sodium chloride additives on alkaline fusion of coal fly ash
    2011
    Co-Authors: Ye Ying
    Abstract:

    The chemical reaction activities of mullite and quartz in coal fly ash were low,which had negative effects on zeolitization and extracting of silica and aluminium elements.Alkaline fusion was an efficient approach for coal fly ash activation.The ash sample was subjected to alkaline fusion treatment using Sodium carbonate and Sodium chloride as additives.Effects of various amounts of additives,alkaline fusion temperatures and time on products were investigated.The fused samples were also characterized by TG-DTA,XRD and SEM.The results show that the phase transformation temperature decreases after adding Sodium carbonate and Sodium chloride into coal fly ash.The mass loss becomes greater in fusion process as well.The addition of Sodium carbonate favors transformation of fly ash into metastable nepheline,while the addition of Sodium chloride favors nepheline to sodalite.The effect of fusion temperatures on products is significant compared with that of fusion time.The fused product Aluminum Sodium Silicate appears as irregular interlocked agglomeration.Sodalite is characterized by sphere-like particles.

  • A New Process for Comprehensive Utilization of High Iron Gibbsite-type Bauxite
    Hydrometallurgy of China, 2014
    Co-Authors: Zhang Yin
    Abstract:

    Based on the mineralogical characteristics of high iron gibbsite-type bauxite from Guangxi and the solubility of Aluminum Sodium Silicate in alkaline solution,a two-stage hydrometallurgical alkaline leaching process for extracting Aluminum and enriching iron was proposed.The results show that the gibbsite could be decomposed by using Sodium aluminate solution with Na2 O of 150g/L,molar ratio of 3.0at 100℃and leaching for 15 min.Leaching of alumina of 72%can be obtained,and at the same time,the mass fraction of hematite is increased by about 20%.The first-stage leaching residue is further treated by pure NaOH solution under the conditions of high temperature,high alkali concentration and high liquid-to-solid ratio.Large portion of Aluminum and silicon can be dissolved into leaching solution and the further enrichment of iron can be realized.After the two-stage alkaline leaching,an iron ore concentrate with a total Fe grade of 61%is gained,in which the main Fe phase is hematite.By the two-stage hydrometallurgical alkaline leaching process,Aluminum and iron can be separated effectively from the high iron gibbsite-type bauxite.
