A method for recovery of metals from Jarosite waste for its effective utilization wherein, the treatment of nitric acid to jarosite waste extracts the nitrates of lead, cadmium, iron, copper, nickel, zinc, aluminum, manganese, cobalt, magnesium and calcium in the filtrate; the treatment of sulfuric acid to the residue obtained from step (a) extracts the metal in the form of ferrous sulfate, aluminum sulfate, zinc sulfate and calcium sulfate in the filtrate; and the treatment of alkali to the residue obtained from step (a) extracts the metal in the form of sodium silicate and sodium aluminate in the filtrate. The silver present in the Jarosite waste as sulfate/silicate is not extracted in nitric acid, sulfuric acid or alkali. Thus, the remaining residue is enriched with silver concentration to at least 2000 ppm, where silver can be easily recoverable and has good commercial value.

Effective utilization of jarosite waste

A biofiller for rubber reinforcement; said biofiller is surface treated up to 10% by weight of microcrystalline lignocellulose with aldehyde and/or ketone. The said biofiller has economic significance as well as reduces pollution as it replaces 2% carbon black from the rubber composition which is substantial amount after reviewing overall use of carbon black in rubber industries such as tyre industry, worldwide. A rubber composition comprising the said biofiller and its various applications such as tyre, shoes, bags, belts, etc.

Articles including a conductive metal substrate and a protective coating on the metal substrate are provided. The protective coating is electrochemically deposited from an electrodeposition medium including a silicon alkoxide and quaternary ammonium compounds or quaternary phosphonium compounds. Methods of electrochemically depositing such protective coatings are also described herein.

Electrodeposition mediums for formation of protective coatings electrochemically deposited on metal substrates

The present invention provides a simple and economical process for preparation of metal-coated non-metallic nano/micro particles. The nano/micro particles are composed of a core and metallic coat over the core using silver or other transition/noble metals. The core of the non-metallic nano/micro particles are selected from inorganic material such as silica, calcium carbonate, barium sulfate, or emulsion grade polyvinyl chloride and other polymers prepared by emulsion process including porous polymers. The metal coating is selected from the transition/noble metals such as copper, nickel, silver, palladium, platinum, osmium, ruthenium, rhodium, and such other metals and their combinations that are easily reducible to elemental metal.
