Periodic Reporting for period 1 - Stibiox (Innovative antimony recovery process from lead and plastics wastes.)
Okres sprawozdawczy: 2018-08-01 do 2019-01-31
Considering that the China's mining production is reducing due to the gradual depletion of mines (from 150 ktons in 2010 to 115 ktons in 2016), it is expected that the world natural resources of this metal will be exhausted in the next 8 years! The scarcity of the raw material availability, the monopolistic position of China and dumping policies lead to an extremely high and unstable cost for plastics and Pb battery European industries.
Finding new solutions for Sb recycling, competitive with the market price of the raw material from Chinese mines, would open the huge market of plastics and LA batteries raw materials supplying. And also find secondary sources of Sb either through the recycling of end-of-life products or by recovering antimony from industrial process residues. The main secondary sources under study are lead-acid batteries, plastics with antimony-containing flame retardants, and “dirty” antimony concentrates containing high quantities of lead.
Stibiox is an innovative process able to recover pure Antimony from the residues of lead metallurgy and from the flame retardants plastics / lead-acid batteries wastes, thanks to a new process composed by a thermal oxidation, a leaching, a liquid/liquid separation and a final desorption. This process will allow a disruptive performance in terms of recycled Sb purity (> 99.9%) and cost of recovery, thereby allowing to sell the recycled antimony in the raw material market at a cheaper and stable price.
