Title: Innovations of Juho K Makinen
Introduction
Juho K Makinen is a notable inventor based in Vanha-Ulvila, Finland. He has made significant contributions to the field of metallurgy, particularly in the treatment of iron-bearing slags and the chlorination of impurity metals. With a total of five patents to his name, Makinen's work has advanced the understanding and processes involved in metal recovery.
Latest Patents
One of his latest patents is a method for treating iron-bearing slags containing precious metals. This invention focuses on reducing slags created during copper and nickel smelting processes. By adding a possible sulphidizing agent, the composition of the molten slag is regulated to achieve a balance between metallicized iron-bearing molten copper sulphide and metallic copper. Controlled cooling allows for the concentration of precious metals into the iron-base metal phase, which can then be separated through magnetic separation. Following this, a selective hydrometallurgic treatment is performed to recover the precious metals.
Another significant patent involves a process for chlorinating the volatilization of impurity metals. This process is designed for raw materials containing oxides of impurity metals and iron. The raw material is heated to over 900 degrees Celsius in an oxidizing atmosphere and contacted with magnesium chloride to chlorinate and volatilize the impurity metals. The purified raw material is then discharged and rinsed to ensure the removal of impurities.
