Co-retarding agents for preparing purified brine

   
   

The invention relates to a process to produce brine of improved purity by dissolving salt that contains a calcium sulfate source in water, in the presence of a retarding agent, while using one or more co-retardants to bind contaminants that could interfere with the retarding agents.

La invención se relaciona con un proceso con la salmuera del producto de la pureza mejorada disolviendo la sal que contiene una fuente del sulfato de calcio en agua, en la presencia de un agente que se retarda, mientras que usa unos o más co-retardadores para atar los contaminantes que podrían interferir con los agentes que se retardaban.
