During the processes where acid and cyanide are used in jewelery workshops, waste gases originates that hazardous in terms of human and environmental health and material. It is necessary to control these originated gas flows with suitable methods and equipment in the workshop and convert them to non-hazardous forms. For this purpose, waste gas washing equipment which can be used by various producers in jewelery workshops are produced. In this study, waste gas stream hazardous emissions removal efficiency of a system produced for this purpose was examined and the measures to be taken for the continuous efficiency were mentioned. According to results; it has been determined that the nitric acid emissions and the sulfuric acid emissions originated from the iron / copper solvation process are reduced by 94.5% and 88.3%, respectively, by means of waste gas washing system. It has been determined that cyanide emissions are reduced by 98.7% by washing the waste gases from the bombing process by means of washing system. According to results, treated toxic gaseous emission concentrations were below the limit. values of Turkish Industrial Air Pollution Control Regulation (TIAPCR) and Netherlands Emission Guidelines for Air (NER).
