Latest Patents
One of Zhang's latest patents is titled "Low-cost selective precipitation circuit for recovery of rare earth elements from acid leachate of coal waste." This invention outlines a process of selective precipitation aimed at recovering rare earth elements from acidic media derived from coal and coal byproducts. The process involves two main steps: sequential precipitation and selective precipitation, with an intermediary step of re-precipitation to further increase rare earth element concentrations and improve contaminant metal removal.
Another significant patent is the "Method for recovering valuable elements from precombustion coal-based materials." This method includes several steps, such as grinding the materials to a predetermined size, roasting them at temperatures between 600°C and 700°C for mineral decomposition, and submerging the roasted materials in a lixiviant solution. The process culminates in filtering the solution to separate residual solids from a pregnant leach solution, which contains the valuable elements, allowing for their recovery and concentration.
