Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for analyzing the mineral composition of copper concentrate before smelting are slow and non-representative due to laboratory-based x-ray fluorescence, which does not provide real-time data, leading to inefficiencies in furnace operations.
Innovation Solution
An in-line x-ray diffraction system that continuously analyzes the dry copper concentrate before it enters the smelting furnace, using a bypass and diffraction equipment to provide real-time mineralogical data, ensuring timely and representative measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If laboratory-based x-ray fluorescence analysis is used, then mineral composition data can be obtained, but the analysis speed is slow and data is not real-time
Solution Approach 1:
The patent replaces the mechanical laboratory-based sampling and analysis system with an in-line x-ray diffraction system that automatically analyzes concentrate as it moves through the conveyor belt, eliminating the need for manual sampling and laboratory processing
Solution Approach 2:
The patent introduces an intermediary measurement chamber with x-ray source and detector that intercepts the moving concentrate stream without stopping it, allowing analysis to occur during normal transport rather than requiring separate laboratory sampling
2Measurement precision
If sporadic laboratory sampling is performed, then mineralogy can be determined, but the measurements are neither timely nor representative
Solution Approach 1:
The patent implements continuous analysis by positioning the x-ray measurement system over the moving conveyor belt, enabling uninterrupted real-time monitoring of concentrate mineralogy as it travels from drying to smelting
Solution Approach 2:
The patent performs analysis before the concentrate enters the smelting furnace, allowing operators to adjust process parameters based on predicted mineral composition rather than reacting to delayed laboratory results
3Productivity
If in-line x-ray diffraction analysis is implemented, then real-time mineralogical data is obtained, but the system complexity increases
Solution Approach 1:
The patent designs the measurement chamber to serve multiple functions: it acts as both a structural support element and an x-ray measurement cell, while the same system handles both data collection and process control feedback
Solution Approach 2:
The patent extracts the measurement function from the complex laboratory analysis system and implements it as a simplified in-line x-ray diffraction cell that operates autonomously during normal conveyor operation
