Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional methods using cyanide or sodium hydrogen sulfide are used to separate molybdenite from copper sulfide minerals, then separation efficiency is improved, but environmental pollution and safety risks worsen due to toxicity
Solution Approach 1:
The patent introduces a novel reagent that acts as an intermediary substance to selectively suppress the flotation of copper sulfide minerals without using toxic cyanide or sodium hydrogen sulfide. This intermediary reagent achieves the same separation function while eliminating environmental pollution and safety risks associated with conventional toxic chemicals.
2Object-affected harmful factors
If ozone oxidation or plasma irradiation methods are used to refine molybdenum mineral, then toxic substance usage is eliminated, but device complexity and practicality worsen due to requirement of specialized equipment
Solution Approach 1:
The patent employs a chemical reagent approach instead of complex physical treatment devices like ozone generators or plasma irradiation equipment. The reagent can be easily applied, used, and disposed of without requiring expensive, complex, and impractical specialized devices, thereby eliminating toxic substance usage while maintaining simplicity and practicality.
3Productivity
If collectors such as kerosene and diesel oil are added to float molybdenite, then flotation efficiency is improved, but environmental safety worsens due to use of hydrocarbon fuels
Solution Approach 1:
The patent changes the chemical parameters of the flotation system by introducing a novel reagent that selectively modifies the surface properties of copper sulfide minerals. This parameter change allows for effective separation without using hydrocarbon collectors like kerosene and diesel oil, thereby maintaining flotation efficiency while improving environmental safety.
