Hermes bags

 
vessel or sHermes Kellyeries of vessels about 15 to 20 ft. square and about 6 ft. deep, I put a layer of alkali waste or other earthy sulphide, about 18 in. deep, through which I cause the liquors to permeate slowly; the silver and copper during this operation combine with the sulphur of the sulphides and the chlorine or acid, andHermes the oxygen in the latter case; and passing over from the metallic salts to the alkaline earthy matters, the metallic sulphides are precipitated, being insoluble in the sulphate liquor; or I allow the solution containing the metallic salts to remain in contact with the precipitant until the metals are precipitated. This operation will usually occupy only an hour or two, but it is desirable that sufficient time be alHermes Birkin in order to obtain deposition of the precipitated matters; this will be ascertained on examining the liquors from time to time. When the precipitation and deposition are complete, the liquor is to be drawn off and the residual product flHermes Handbagsuxed to convert the silver and copper into regulus. The black or green ash, herein described, may be used in the solid form in a similar manner to that described when using alkaline earthy sulphide; but I prefer to make a Hermes outletstrong and hot solution, and having ascertained the quantity of silver and copper in the sulphate solution, I run a quantity of the sulphide solutiou into a vessel or set of vessels, and then add the sulphate solution thereto. Hermes bagsIf the whole of the silver and copper are not precipitated, I add a further quantity of the precipitant. When the precipitate is fully subsided, I carefully draw off or filter the sulphate liquor which is to be used in the manufacture of sulphate of soda, and for the purposes to which sulphate of soda is usually applied. When the precipitate is sufficientlyBirkin accumulated, I wash and dry it, and proceed to heat the precipitate, as herein described, to manufacture silver and sulphate of copper, or silver and copper, as the ease may be.
