SILVER EXTRACTION FROM WASTES
Introduction
Silver is a very precious and important metal extensively used in photography, X- ray films, jewelry, electrical materials, medicine, etc. In the modern era, silver extraction from waste material has caught the imagination of scientists and engineers. Today, silver is extracted from the waste solution of X-ray clinics, photographers, block makers, and offset printers. Project cost is US$13,925 with a production capacity of 45Kgs per annum and yielding estimated revenues of US$377 per year.
Production Process, Capacity and
Technology
The silver extraction machine has simplified the process of drawing silver from waste. Firstly, the silver concentration is checked on site with the silver estimation paper in grams per litre. Based on the silver estimation, purchase rates are fixed. The waste solution is first filled in the machine, the moment the machine is switched on, and the silver present in the solution gets deposited on the collecting blocks. In a stipulated time, the silver on the collecting blocks is obtained in pure form. Minimum capacity of 45 kg per annum working 26 days in a month.
Market Analysis
Silver can be sold anywhere at around $250 per kg. This is very promising as the raw materials could even be got for free as waste and the potential for exporting is high. There are no key payers in this field yet in this country.
