Abstract
The invention relates to a process for gathering heavy rare noble metal by a hushing method, which is applicable to recovering a small amount of residual noble metal contained in waste strut. The process comprises the following steps of: step 1. grinding: grinding materials (holding brick) in a grinder into brick blocks with the diameter of 3-5cm; step 2. wet grinding: placing the brick block with the diameter of 3-5cm in a ball mill and wet grinding the block to 200 meshes of fine powder under a water environment; step 3. gathering: placing the 200 meshes of fine powder in a washing groove for washing and separating with the water at a certain rate; and step 4: purifying: placing the material gathered in the step 3 in a glass container and adding a proper amount of chemical reagent to remove ordinary metal. The invention has the advantages of no pollution, high gathering level, high purity of the product, and the like.
Description
Technical field
The present invention relates to a kind of process for gathering heavy rare noble metal by hushing method, be applicable to the recovery that contains the precious metal of minimal residue in the useless upholder.Belong to wet method extractive technique field.
Background technology
In recent years China's fiber glass industry has had significant progress, the crucible bushing that is formed by platinum rhodium materials processing is an indispensable key device during glass fibre is produced, generally about 1200 ℃, platinum rhodium partly volatilizees among upholder-holder brick its processing temperature after the long-time continuous operation.Thereby be the important topic that people study from the recovery that useless holder brick etc. contains rare precious metal.The method of existing employing has: sintering process, metal method of trapping, sodium hydroxide scorification, gravity treatment partition method etc., and the investment that these methods have is big, and the intermediate materials consumption that has is big, and the complex process and the yield that have are low, and middle material is contaminate environment also.As the sodium hydroxide scorification is that holder brick and sodium hydroxide mixing are packed in the iron crucible, makes it become water-soluble substance after 500-700 ℃ of condition fusion, again hydrometallurgic recovery platinum from undissolved residue.So designing a kind of technology, simply to save the precious metal recovery method of intermediate material imperative.
Summary of the invention
To reclaim yield in order promoting, save middle consumptive material, to reduce pollution, the invention provides a kind of process for gathering heavy rare noble metal by hushing method environment.
To achieve these goals, technical scheme of the present invention comprises step 1 pulverizing: place pulverizer to be ground into the fragment that diameter is 3-5cm raw material (holder brick); Step 2 wet-milling: with diameter is that 3-5cm fragment raw material places ball mill thin foam of wet-milling to 200 order under the environment of band water; Step 3 enrichment: the thin foam raw material of 200 orders placed wash away ditch and wash away separation with the water of given pace; Step 4 is purified: will place Glass Containers through the former reality after step 3 enrichment, and add an amount of chemical reagent and remove plain metal.It is characterized in that the thin foam raw material of 200 orders placed and wash away ditch and wash away separation with the water of given pace.The described long 2500mm-3000mm of ditch, the wide 500mm-600mm of washing away; The described bottom, water side of washing away ditch is provided with the baffle plate of suitable height; Cross section, ditch bottom, described road is a circular arc; The speed of described flush water is 0.9-1.1m/s.
That the present invention has is pollution-free, enrichment degree is high, the product purity advantages of higher.
Embodiment
Getting an amount of holder brick (refractory materials of support manufacturing glass fiber crucible bushing), to place pulverizer to carry out cutting and grinding be the 3-5cm fragment to diameter, then fragment is placed ball mill, and adding a certain amount of water, to carry out ball milling be thin foam about 200 orders to diameter.Thin foam about above-mentioned 200 orders is placed among the coombe road of about 2.5m, wide about 0.6m, and float filtration, obtain platinum content higher (about's more than 95%) metal particle, get purity through chemical removal impurity again and reach 99.9% platinum with the water flushing of 1m/s speed.
Claims (4)
1. a process for gathering heavy rare noble metal by hushing method comprises step 1 pulverizing: place pulverizer to be ground into the fragment that diameter is 3-5cm raw material (holder brick); Step 2 wet-milling: with diameter is that 3-5cm fragment raw material places ball mill thin foam of wet-milling to 200 order under the environment of band water; Step 3 enrichment: the thin foam raw material of 200 orders placed wash away ditch and wash away separation with the water of given pace; Step 4 is purified: will place Glass Containers through the former reality after step 3 enrichment, and add an amount of chemical reagent and remove plain metal, it is characterized in that with about 200 orders carefully the foam raw material place and wash away ditch and wash away separation with the water of given pace.
2. a kind of process for gathering heavy rare noble metal by hushing method according to claim 1, the speed that it is characterized in that described flush water is 0.9--1.1m/s.
3. a kind of process for gathering heavy rare noble metal by hushing method according to claim 1 is characterized in that the described long 2500mm--3000mm of ditch, the wide 500mm--600mm of washing away.
