Precious Metal Separation with Ferromagnetic Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing precious metal separation systems face inefficiencies in separating gold and other precious metals from granular mixtures containing ferromagnetic materials, as these systems often process unnecessary non-precious materials, leading to reduced effectiveness and potential loss of valuable metals.
Innovation Solution
A system comprising a feeder that provides a granular mixture to a precious metal separator device, equipped with a remover that magnetically attracts and collects ferromagnetic materials before they reach the separator, allowing for adjustable rotation speed and angle of the feeder outlet and magnet rotation to optimize the separation process, and a shaker table with differential motion and grooves to separate precious metals based on weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a precious metal separator device processes granular mixture containing ferromagnetic materials, then the separator can process the entire mixture, but the separation effectiveness decreases due to processing unnecessary non-precious materials
Solution Approach 1:
The patent applies preliminary action by placing a magnetic remover in front of the precious metal separator to remove ferromagnetic materials from the granular mixture before it reaches the separator. This preliminary removal of unwanted ferromagnetic materials allows the separator to focus only on separating precious metals from non-ferromagnetic materials, thereby improving separation effectiveness while maintaining processing capacity.
2Productivity
If ferromagnetic materials are present in the granular mixture, then the mixture can be processed as-is, but the load on the separator device increases unnecessarily
Solution Approach 1:
The patent applies the extraction principle by using a magnetic remover to extract and remove ferromagnetic materials from the granular mixture before the mixture enters the precious metal separator. This extraction of ferromagnetic materials reduces the unnecessary load on the separator device, allowing it to operate more efficiently with a reduced workload while maintaining the same processing rate.
3Device complexity
If the feeder outlet angle and magnet rotation speed are fixed, then the device structure is simple, but the separation efficiency cannot be optimized for different conditions
Solution Approach 1:
The patent applies dynamics by making the feeder outlet angle and magnet rotation speed adjustable rather than fixed. This allows the system to adapt to different granular mixture conditions and optimize separation efficiency for various scenarios. The dynamic adjustability comes with minimal added complexity, as the adjustments can be made through simple mechanical means while significantly improving separation efficiency.

AI summary
A system for precious metal separation includes a feeder that provides a granular mixture to a precious metal separator device. The feeder includes an inlet port, a storage area, and an outlet port. The feeder provides the granular mixture to the precious metal separator device at a rate at which the precious metal separator device processes the granular material. As the feeder provides the granular mixture to the precious metal separator, a remover removes ferromagnetic material from the provided granular mixture before the provided granular mixture reaches the precious metal separator.
