Gold Refining System

Introduction to gold Refining :

K-JHIL – believes that mastery over jewellery craftsmanship is incomplete, without your total control over the caratage of your gold. Our complete in-house gold refining systems, provide you full control over this primary and crucial process. Infact, it is the first step to the perfection of your glittering end products.

Gold Refining System

K-JHIL – gold refining systems are ideal for old gold jewellery buyers, bullion suppliers, gold smithies, jewellery casting and chain manufacturing factories, job-work refineries etc., as they come in various capacities, to suit small or larger refining needs of the jewellery trade.

K-JHIL – series of gold refining systems are among the most advanced in-house refining systems available,with special features not found in other gold refiners. Jewellers worldwide and in India, have understood the many advantages of in-house refining and are appreciating the profits, by savings, otherwise not achieved due to low yields and/ or purity, idle storage of refinable gold, high refining charges, etc.

Gold Refining System

K-JHIL’s 4 simple steps to get pure Gold :

  • Dissolution : Acids react with gold, silver, copper and other alloy constituents to form gold chloride solution, silver chloride precipitate and copper nitrate solution.
  • Filteration : Silver chloride precipitate and insoluble matter is seperated from solution containing dissolved gold and copper.
  • Reduction : Gold reagent, added to solution, reduces gold chloride to pure gold oxide precipitate.
  • Washing : Gold oxide is removed from the remaining solution containing dissolved copper, is chemically washed and dried. You can now melt the gold powder and re-use as required.

Process Advantages :

  • The simplest, most versatile refining process.
  • Yields virtually 100% of your gold. Purity upto 99.99% can be
  • achieved.
  • Electrolytic refining process disadvantages, such as inconsistent
  • yields and purity, very slow refining speed, only part recovery per
  • batch, only refines carat gold, very expensive inputs per gram of
  • refining etc., do not arise here.
  • Absolutely no silver addition necessary.
  • Silver and copper in your gold alloy, recoverable.
  • Low consumption of HCl and HNO3 acids.
  • Refines carat gold, e.g. old gold jewellery, gold scrap, lemels, rolling
  • strips, granules, facetting dust, lead contamination, etc.
  • Recovers from low grade gold wastes, eg. floor sweeps, buffing
  • rouge powder, filings, grindings, polishings, wash slurry, crucible
  • powder, etc.

Industrial Bromine Recovery Plant

Features:

  • Precisely designed
  • Excellent performance
  • High reliability

Process Description

The feed is acidified with 30% HCI acid and acidified feed is fed to the scrubber by pump to Scrub uncondensed chlorine from Vent Condenser and return back to the reaction column. In some cases the part feed is preheated using effluent from the reaction column prior to the entry of reaction column and part feed is fed to the scrubber to conserve energy. Chlorine and Steam are also fed to the reaction Column.

In the reaction column the feed is reacted with chlorine gas & bromine is liberated Instantly. This liberated bromine is stripped out of the solution by live steam. The bromine and water vapor stream leaves the top of the column and enters the condenser. Condensate falls into the Phase Separator where it forms two phases, the light aqueous phase (Water) being returned to the Column ,while the heavy phase(Bromine) being feed the purification column. Cooling Water & Chilled Water is used as cooling media in heat exchanger provided at the top of the column to condense water vapor & Bromine.

Purification of the Bromine is achieved by distillation. Heat being introduced into the column through the reboiler. Bromine and Chlorine vapor leave the top of the Column and enter the Condenser .The Bromine gets condensed in the Condenser and falls back into the column while uncondensed chlorine vapor along with traces of Bromine escapes from the Condenser and enter into the Vent Condenser, where remaining Bromine gets condensed and back to the crude Bromine receiver. Pure bromine is cooled in a product cooler and goes to Product receivers. Guard condenser is also provided atthe top of the receiver to prevent escape of bromine. Bromine is then collected in glass bottles.

From Industrial Effluents (NaBr/KBr/HBr) From Sea -Bittern. Available up to 600 mm Dia.

  • The plant has been designed as a continuous process to produce dry HCl gas by the process of distillation of 30% hydrochloric acid solution along with a co-current stream of calcium chloride solution.
  • A pre-heated stream of 30% hydrochloric acid solution is fed to the azeotropic distillation column (C-1). Simultaneously a co-current feed of concentrated calcium chloride is also fed to the distillation column.
  • The calcium chloride breaks the azeotrope formed between HCl and water and as a result almost all the HCl available in the soln. is released as gas.
  • The heat exchangers (E-2 and E-4) are designed as thermosyphon reboilers where the heat energy for the distillation process and the evaporation process is supplied by steam.
  • The vapour from the reboiler strips the available gas from the feed acid soln. in the column. The top product HCl gas is dried in the Drying Unit using a suitable dehydrating agent. The moisture content in the product HCl gas is expected to be less than 0.001%.
  • The bottom product from the column (C-1) is dilute calcium chloride solution with some HCl content. The dilute CaCl2 soln. is concentrated in the evaporator (E-4) and the re-concentrated CaCl2 soln. is recycled to the distillation column by pump (P-2).
  • The vapour from the evaporation process consists of water and expected to contain less than 1% HCl. This water vapour is condensed in the heat exchanger (E-5) prior to discharge.
  • The system selected is very stable.
  • Once all the operating conditions are stabilized and maintained; rate of generation of HCl gas depends only upon rate of hydrochloric acid (30%) feed.
