Extracting Worth From Waste

1. Blog 1: Globalrefininggroup.com EXTRACTING WORTH FROM WASTE Catalytic converters are used in the automobiles to reduce emission.Acatalytic converter can be easily removed from your vehicle without much trouble. Many industries nowadays are paying to buy old unusable catalytic converters. Thesescrap catalytic converterscan be sold to the organizations which collect them in bulk. You can sell your old catalytic converters to one of the companies that recycle these devices. Companies like these use the process of catalytic converter smelting to remove catalytic metals from it, which can be used for further processes afterwards. After collection, catalytic converter de-canning is done, in which the ceramic structure is separated from the steel can.After this process,the ceramic substrate and the metal part are weighed and sampled to get an estimate as to how much precious metal can actually be extracted from it. The process of value calculation is known as “Assaying”, and depending upon the need of the customer it can be done in two labs, one of which is the customer’s choice, so that a negotiated price of the commodity can be agreed upon by both the parties. After this, the assayed product goes through the process of smelting. Catalytic converter smelting is the process in which the assayed sample is crushed into small pieces and heated to its melting temperature. A substance known as “Platinum group metal flux” is added to the melt; the slag of this is removed and heated again till the lead from the slag is absorbed and what remains is a bead of precious metal. This sounds more complicated than it actually is!
