silver extraction process by using sodium sulfide from xray

USA Process for improving the extraction yield of How to Extract Silver Sapling

A process for the extraction of silver and gold from refractory ore is disclosed The process includes first grinding the refractory ore This ground refractory ore is subsequently treated with an alkali solution of a stoichiometric excess amount of sulphide in relation to the amount of gold and silver contained in the refractory ore to thus form a pulp containing a gold and silver sulfideNov 22 32 Extract Silver Step Buy or build an electrolysis machine This machine will help you to extract silver from your waste chemicals You can find electrolysis machines in science supply stores or you can make your own using a 12 volt charger and a rubber tub

silver Ag Recovering Silver from Hypo fixer solution of Medical X

Silver Ag is a lustrous white ductile malleable metallic elementIt is also a noble metal and a transition element occurring in group IB of the periodic tableIt has the highest thermal and electrical conductivity of any metal Silver occurs both uncombined sa native silver see Figure 1 and in ores such as galena and argentiteApr 05 32 The trick of this process is to determine silver content to add the correct amount of Na2S as simple like thisIf you add more Na2S than needed then you will form H2SNo need to use NaOH for common fixers used in photo processes and X ray You do not need silver estimating paper copper wire will do the job nicelyLooking at your copper wires I
