锂辉石——石灰石烧结法生产单水氢氧化鲤流程中,锂辉石精矿配加石灰石制备出合格生料浆以后,在回转窰内烧结为熟料,是本流程中关鍵的一步。烧成的好坏及化学反应的完全与否,关系到熟料的质量,直接影响以后的工艺过程和金属总回收率的高低。关于烧成化学反应的研究,国外文献报道不多,资料不系统。对鲤辉石——石灰石烧结主要化学反应,基本上有两种看法。1946年Nicholson在美国专利U·S2,413,644[1][2]中,推测在1100℃时,锂辉石——石灰石发生下列反应: Li_2O·Al_2O_3·4siO_2+9CaO=Li_2O+CaO·Al_2O_3+4[2CaO·SiO_2] (1)即在烧结时,生成游离的氧化锶,铝酸鈣和二鈣硅酸,也即在烧结过程中,发生了锂辉石中 Spodumene - Limestone Sintering Process for the Production of Single Hydrogenated Carp, Sintered Spirits in a Rotary Kiln, after Spodumene Concentrate with Limestone Prepared as Qualified Raw Slurry, is a Crucial Step in this Process . The quality of the firing and the chemical reaction is complete or not, related to the quality of clinker, a direct impact on the subsequent process and the level of total metal recovery. About the study of firing chemical reaction, few reports in foreign literature, the information is not systematic. On the carp pyroxene - limestone main chemical reactions, there are basically two views. In 1946, Nicholson in U.S. Patent U. S2,413,644 [1] [2], speculated that at 1100 ℃, spodumene - limestone the following reaction: Li_2O · Al_2O_3 · 4siO_2 + 9CaO = Li_2O + CaO · Al_2O_3 +4 [2CaO · SiO_2] (1) That is, in the sintering, the formation of free strontium oxide, calcium aluminate and dicalcium silicate, that is, in the sintering process, the occurrence of spodumene
