    摘要： Embodiments relate to methods, systems And apparatus tor generating lithium from brine. The brine is heated in a first vessel to greater than 260° C. and CO2 gas is injected mixing with the brine such that the CO2/P is greater than 18 g/atm. The brine is held at greater than 18 g/atm for longer than 20 minutes so that any impurities precipitate as solids leaving only lithium ions and chlorine ions. The brine is moved to a second vessel screening out solid precipitates leaving a brine containing only chlorine and lithium. CO2 gas is injected and mixed with the brine at 260° C. so that the CO2/P is greater than 200 g/atm. The brine is held at greater than 200 g/atm for longer than 20 minutes suppressing the chlorine as dissolved ions while lithium precipitates out as lithium carbonate. The lithium carbonate precipitate is removed from the brine solution.

    摘要： Aluminum-strontium enriched master alloy granules for use primarily in modifying the eutectic phase in aluminum-silicon casting alloys. The master alloy granules are predominantly intermetallic compounds Al.sub.4 Sr, Al.sub.2 Sr or Alsr and mixtures thereof. By using such intermetallic dominant alloys in a granulated state rapid dissolution in aluminum-silicon alloy melts is achieved. The master alloy composition can be directly added to a content of the melt or injected into it. The master alloy composition can also be mixed with aluminum granules and extruded into a rod or entrained into a billet of cast aluminum.
