An extensive exptl. campaign on Li recovery from relatively dilute LiCl solutions (i.e., Li+ ~4000 ppm) is presented to identify the best operating conditions for a Li2CO3 crystallization unit. Lithium is currently mainly produced via solar evaporation, purification, and precipitation from highly concentrated Li brines located in a few world areas. The process requires large surfaces and long times (18-24 mo) to concentrate Li+ up to 20,000 ppm. The present work investigates two separation routes to extract Li+ from synthetic solutions, mimicking those obtained from low-content Li+ sources through selective Li+ separation and further concentration steps: (i) addition of Na2CO3 solution and (ii) addition of NaOH solution + CO2 insufflation. A Li recovery up to 80% and purities up to 99% at 80°C and with high-ionic strength solutions was achieved employing NaOH solution + CO2 insufflation and an ethanol washing step. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Computed Properties of ClLi).
Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Computed Properties of ClLi
