Abstract
The present invention relates to a kind of new recovery noble metal technique, the recovery of the noble metal containing minimal residue suitable for the supporter that gives up.Belong to wet underwater welding technical field.Crushed including step 1：By raw material（Hold in the palm brick）It is placed in pulverizer and is ground into a diameter of 3 5cm fragment；Step 2 wet-milling：A diameter of 3 5cm fragment raw materials are placed in ball mill in the environment of band water wet-milling to the thin foam of 200 mesh；Step 3 is enriched with：The thin foam raw material of 200 mesh is placed in wash away in ditch and carries out washing away separation with the water of given pace；Step 4 purifies：Raw material after step 3 is enriched with is placed in glass container, adds appropriate chemical reagent removing common metal.The present invention has the advantages that pollution-free, enrichment degree is high, product purity is high.
Description
Technical field
The present invention relates to a kind of new recovery noble metal technique, particularly one kind to wash away method recovery noble metal method, the recovery of the noble metal containing minimal residue suitable for the supporter that gives up.Belong to wet underwater welding technical field.
Background technology
At present, China's fiber glass industry has significant progress, the crucible bushing being process by platinum-rhodium alloy material is indispensable key device in glass fibre production, its processing temperature is typically at 1200 DEG C or so, and the volatilization of platinum-rhodium alloy part is among supporter-support brick after working continuously for a long time.It is thus the important topic of people's research from recovery containing rare precious metal such as useless support bricks.The method of existing use has：Sintering process, metal method of trapping, sodium hydroxide fusion method, Gravity separation method etc., the investment that these methods have is big, and some intermediate materials consumptions are big, some complex process and yield is low, and middle material also pollutes environment.If sodium hydroxide fusion method is that support brick and sodium hydroxide are mixed to be fitted into iron crucible, so that it becomes water-soluble substance after 500-700 DEG C of condition melting, then the hydrometallurgic recovery platinum from insoluble residue.So design a kind of technique simply save intermediate material method for recovering precious metals it is imperative.
The content of the invention
In order to lift recovery yield, save middle consumptive material, pollution of the reduction to environment, the invention provides a kind of new recovery noble metal technique.
To achieve these goals, technical scheme crushes including step 1：By raw material（Hold in the palm brick）It is placed in pulverizer and is ground into a diameter of 3-5cm fragment；Step 2 wet-milling：A diameter of 3-5cm fragments raw material is placed in ball mill in the environment of band water wet-milling to the thin foam of 200 mesh；Step 3 is enriched with：The thin foam raw material of 200 mesh is placed in wash away in ditch and carries out washing away separation with the water of given pace；Step 4 purifies：Raw material after step 3 is enriched with is placed in glass container, adds appropriate chemical reagent removing common metal.Carry out washing away separation with the water of given pace it is characterized in that the thin foam raw material of 200 mesh is placed in wash away in ditch.Described washes away the long 2500mm--3000mm of ditch, wide 500mm -600mm；The described water side bottom for washing away ditch is provided with the baffle plate of appropriate height；The Dao Gou bottom sections are circular arc；The speed of described flush water is 0.9-1.1m/s.
The present invention has the advantages that pollution-free, enrichment degree is high, product purity is high.
Embodiment
Take appropriate support brick（The refractory material of support manufacturing glass fiber crucible bushing）It is placed in pulverizer and carries out cutting and grinding to a diameter of 3-5cm fragments, then fragment is placed in ball mill, and add a certain amount of water and carry out ball milling to the thin foam of a diameter of 200 mesh or so.The thin foam of above-mentioned 200 mesh or so is placed among about 2.5m, width about 0.6m coombe road, and drift filtering is rinsed with the water of 1m/s speed, it is higher to obtain platinum content（About more than 95%）Metal particle, then obtain purity up to 99.9% platinum through chemical removal impurity.
Claims (4)
1. a kind of new recovery noble metal technique, including step 1 crush：By raw material（Hold in the palm brick）It is placed in pulverizer and is ground into a diameter of 3-5cm fragment；Step 2 wet-milling：A diameter of 3-5cm fragments raw material is placed in ball mill in the environment of band water wet-milling to the thin foam of 200 mesh；Step 3 is enriched with：The thin foam raw material of 200 mesh is placed in wash away in ditch and carries out washing away separation with the water of given pace；Step 4 purifies：Raw material after step 3 is enriched with is placed in glass container, adds appropriate chemical reagent removing common metal, it is characterised in that is placed in wash away in ditch by the thin foam raw material of 200 mesh or so and carries out washing away separation with the water of given pace.
2. a kind of new recovery noble metal technique according to claim 1, it is characterised in that the speed of described flush water is 0.9-1.1m/s.
3. a kind of new recovery noble metal technique according to claim 1, it is characterised in that described washes away the long 2500mm--3000mm of ditch, wide 500mm -600mm.
4. a kind of new recovery noble metal technique according to claim 1, it is characterised in that the described water side bottom for washing away ditch is provided with the baffle plate of appropriate height.
