Effect of sodium aluminate on chromium spinels oxidation in chromite lime-free roasting process
The reaction between Na2O·Al2O3 and chromium spinels or chromite in the roasting process was systemically investigated to reveal the effects of Na2O·Al2O3 on chromium oxidation. The results of Na2O·Al2O3 roasted with MgO·Cr2O3 illustrate that only about 50% of the chromium in MgO·Cr2O3 can convert i...

| 520 | |a The reaction between Na2O·Al2O3 and chromium spinels or chromite in the roasting process was systemically investigated to reveal the effects of Na2O·Al2O3 on chromium oxidation. The results of Na2O·Al2O3 roasted with MgO·Cr2O3 illustrate that only about 50% of the chromium in MgO·Cr2O3 can convert into Na2CrO4, while the remaining chromium converts into an Al-bearing spinel Mg(CrAl)O4. Mg(CrAl)O4 is found to be difficult to further react with Na2O·Al2O3. The oxidative roasting of Na2O·Al2O3 with chromite further confirms that Na2O·Al2O3 cannot fully react with some chromium spinels, which reveals the cause of the low chromium oxidation rate in the traditional chromite lime-free roasting process. Based on the experiment results, a strategy for eliminating the impacts of Na2O·Al2O3 in the lime-free roasting process was proposed, in which adding more Na2CO3 for forming Na2O·Al2O3 is considered. The chromium oxidation rate can rise close to 100% with the new strategy. This study contributes to better understanding the chromite lime-free roasting process and provides a new idea for developing the chromate salts manufacturing process more efficiently and cleanly. | ||

Based on the experiment results, a strategy for eliminating the impacts of Na2O·Al2O3 in the lime-free roasting process was proposed, in which adding more Na2CO3 for forming Na2O·Al2O3 is considered. The chromium oxidation rate can rise close to 100% with the new strategy. This study contributes to better understanding the chromite lime-free roasting process and provides a new idea for developing the chromate salts manufacturing process more efficiently and cleanly. chromate sodium aluminate chromite chromium spinel oxidative roasting LI, Yao-min verfasserin aut WANG, Peng verfasserin aut LI, Xiao-bin verfasserin aut PENG, Zhi-hong verfasserin aut LIU, Gui-hua verfasserin aut ZHOU, Qiu-sheng verfasserin aut Enthalten in Transactions of Nonferrous Metals Society of China Changsha : NFsoc, 1993 33, Seite 2497-2510 Online-Ressource (DE-627)513219242 (DE-600)2238689-0 (DE-576)284926736 1003-6326 nnns volume:33 pages:2497-2510 GBV_USEFLAG_U GBV_ELV SYSFLAG_U FID-ASIEN GBV_ILN_11 GBV_ILN_20 GBV_ILN_22 GBV_ILN_23 GBV_ILN_24 GBV_ILN_31 GBV_ILN_32 GBV_ILN_39 GBV_ILN_40 GBV_ILN_60 GBV_ILN_62 GBV_ILN_63 GBV_ILN_65 GBV_ILN_69 GBV_ILN_70 GBV_ILN_73 GBV_ILN_74 GBV_ILN_90 GBV_ILN_95 GBV_ILN_100 GBV_ILN_105 GBV_ILN_110 GBV_ILN_120 GBV_ILN_121 GBV_ILN_138 GBV_ILN_150 GBV_ILN_151 GBV_ILN_152 GBV_ILN_161 GBV_ILN_170 GBV_ILN_206 GBV_ILN_213 GBV_ILN_224 GBV_ILN_230 GBV_ILN_285 GBV_ILN_293 GBV_ILN_370 GBV_ILN_374 GBV_ILN_602 GBV_ILN_647 GBV_ILN_702 GBV_ILN_2001 GBV_ILN_2003 GBV_ILN_2004 GBV_ILN_2005 GBV_ILN_2006 GBV_ILN_2007 GBV_ILN_2008 GBV_ILN_2009 GBV_ILN_2010 GBV_ILN_2011 GBV_ILN_2014 GBV_ILN_2015 GBV_ILN_2018 GBV_ILN_2020 GBV_ILN_2021 GBV_ILN_2025 GBV_ILN_2026 GBV_ILN_2027 GBV_ILN_2031 GBV_ILN_2034 GBV_ILN_2036 GBV_ILN_2037 GBV_ILN_2048 GBV_ILN_2050 GBV_ILN_2055 GBV_ILN_2056 GBV_ILN_2057 GBV_ILN_2059 GBV_ILN_2061 GBV_ILN_2064 GBV_ILN_2065 GBV_ILN_2068 GBV_ILN_2088 GBV_ILN_2093 GBV_ILN_2110 GBV_ILN_2111 GBV_ILN_2113 GBV_ILN_2119 GBV_ILN_2129 GBV_ILN_2147 GBV_ILN_2148 GBV_ILN_2152 GBV_ILN_2190 GBV_ILN_2336 GBV_ILN_2470 GBV_ILN_2507 GBV_ILN_2522 GBV_ILN_2548 GBV_ILN_2700 GBV_ILN_2817 GBV_ILN_4012 GBV_ILN_4035 GBV_ILN_4037 GBV_ILN_4046 GBV_ILN_4112 GBV_ILN_4125 GBV_ILN_4126 GBV_ILN_4242 GBV_ILN_4246 GBV_ILN_4249 GBV_ILN_4251 GBV_ILN_4277 GBV_ILN_4305 GBV_ILN_4306 GBV_ILN_4307 GBV_ILN_4313 GBV_ILN_4322 GBV_ILN_4323 GBV_ILN_4324 GBV_ILN_4325 GBV_ILN_4326 GBV_ILN_4333 GBV_ILN_4335 GBV_ILN_4336 GBV_ILN_4338 GBV_ILN_4346 GBV_ILN_4367 GBV_ILN_4392 GBV_ILN_4393 GBV_ILN_4700 GBV_ILN_4753 AR 33 2497-2510 |

The results of Na2O·Al2O3 roasted with MgO·Cr2O3 illustrate that only about 50% of the chromium in MgO·Cr2O3 can convert into Na2CrO4, while the remaining chromium converts into an Al-bearing spinel Mg(CrAl)O4. Mg(CrAl)O4 is found to be difficult to further react with Na2O·Al2O3. The oxidative roasting of Na2O·Al2O3 with chromite further confirms that Na2O·Al2O3 cannot fully react with some chromium spinels, which reveals the cause of the low chromium oxidation rate in the traditional chromite lime-free roasting process. Based on the experiment results, a strategy for eliminating the impacts of Na2O·Al2O3 in the lime-free roasting process was proposed, in which adding more Na2CO3 for forming Na2O·Al2O3 is considered.

The results of Na2O·Al2O3 roasted with MgO·Cr2O3 illustrate that only about 50% of the chromium in MgO·Cr2O3 can convert into Na2CrO4, while the remaining chromium converts into an Al-bearing spinel Mg(CrAl)O4. Mg(CrAl)O4 is found to be difficult to further react with Na2O·Al2O3. The oxidative roasting of Na2O·Al2O3 with chromite further confirms that Na2O·Al2O3 cannot fully react with some chromium spinels, which reveals the cause of the low chromium oxidation rate in the traditional chromite lime-free roasting process. Based on the experiment results, a strategy for eliminating the impacts of Na2O·Al2O3 in the lime-free roasting process was proposed, in which adding more Na2CO3 for forming Na2O·Al2O3 is considered. The chromium oxidation rate can rise close to 100% with the new strategy. This study contributes to better understanding the chromite lime-free roasting process and provides a new idea for developing the chromate salts manufacturing process more efficiently and cleanly.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">chromate</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">sodium

Effect of sodium aluminate on chromium spinels oxidation in chromite lime-free roasting process |
| abstract |
The reaction between Na2O·Al2O3 and chromium spinels or chromite in the roasting process was systemically investigated to reveal the effects of Na2O·Al2O3 on chromium oxidation. The results of Na2O·Al2O3 roasted with MgO·Cr2O3 illustrate that only about 50% of the chromium in MgO·Cr2O3 can convert into Na2CrO4, while the remaining chromium converts into an Al-bearing spinel Mg(CrAl)O4. Mg(CrAl)O4 is found to be difficult to further react with Na2O·Al2O3. The oxidative roasting of Na2O·Al2O3 with chromite further confirms that Na2O·Al2O3 cannot fully react with some chromium spinels, which reveals the cause of the low chromium oxidation rate in the traditional chromite lime-free roasting process. Based on the experiment results, a strategy for eliminating the impacts of Na2O·Al2O3 in the lime-free roasting process was proposed, in which adding more Na2CO3 for forming Na2O·Al2O3 is considered. The chromium oxidation rate can rise close to 100% with the new strategy. This study contributes to better understanding the chromite lime-free roasting process and provides a new idea for developing the chromate salts manufacturing process more efficiently and cleanly. |
