With a total of three patents to his name, Honkala has demonstrated an unwavering commitment to advancing technologies that enhance the exploitation and treatment of complex ores and materials.

Latest Patents

Honkala's latest innovations include a process for the exploitation of low-grade oxidic and iron-bearing complex ores. This process involves reducing initial materials in a rotary kiln at temperatures ranging from 1000°C to 1500°C. The result is a magnetic fraction primarily comprising iron, along with a non-magnetic oxide fraction that can be further exploited using conventional methods.

Another significant patent by Honkala focuses on the treatment of raw materials containing oxides and ferrites of zinc, copper, and cadmium. This method entails neutral leaching with a sulfuric-acid-bearing solution to leach the oxides while minimizing the dissolution of ferrites. The ferrite-bearing residue is then processed, allowing for the precipitation of iron as jarosite and the conversion of zinc to zinc sulfate under controlled thermal conditions.
