We represent Pionera (www.pionera.com) in various countries in Africa and we are studying the efficacy of their biopolymers in viscosity modification, flotation and leaching applications. Pionera have developed a range of unique products based on substitution of a hydroxyphenyl propane monomer. The properties of the products vary depending on the degree and type of substitution. In Africa where many of the new projects are treating oxidized ores, often with a relatively high clay content these polymers are able to assist with plant throughput and leaching efficiency.
