The pulping consisted of disintegration of the wastepaper structure and dispersion of the fibers. The disintegration was accomplished by conditioning 250 grams of wastepaper, under moderate agitation, with hot steam 84 to 90 C, deionized water and reagent as desired. After disintegration the pulp was further dispersed in a high speed blender. All pulping experiments were done at a
A tonne of ore from a gold mine produces just 5 grams 0.18 ounce of gold on average, whereas a tonne of discarded mobile phones can yield 150 grams 5.3 ounce or more, according to a study by
View MoreMobile phones can be recycled at the end of their life.. Rapid technology change, low initial cost, and even planned obsolescence have resulted in a fastgrowing surplus, which contributes to the increasing amount of electronic waste around the globe.

View MoreA metric ton of cell phone handsets could yield 340 grams of gold enough to bring in a sizable profit for anyone with the proper resources for handling largescale recycling and extracting precious metals from mobile phones.
View MoreOften claimed is the idea that the gold recycled from cell phones and other electronic ewaste is of a much higher gold percentage than mined ore grams per tonne. While this may be true, consider that we humans mine about 3,000 tonnes of new line gold every year.
View MoreThe ores from which silver and gold are recoverable by flotation divide themselves naturally into two general processing classes ores in which the valuable minerals are those of the base metals, the precious metals being incidental constituents, and ores in which the gold and silver are of primary importance, the basemetal minerals, if present, being of little or no value. The first class
View MoreIn goldrich ore deposits, there are concentrations of gold at one or two parts per million, That equates to 1g or 2g per tonne. And the idea that 41 handsets contain 1g of gold stems from a UN report on electronic waste. a tonne of old phones weighed without their batteries yields about 300g of gold.
View MoreCompared to the mountainous pile of 17 tons of gold ores, more gold can be recovered from this heap during cell phone recycling than what can be extracted from 17 tons of gold ores. A ton of cell phones can yield as much as 280 grams of gold, about 140 grams of platinum and palladium, and 140 kilograms of copper.

View MoreThe mobile phone has become an indispensable tool of modern life, and new models appear every year like automobiles in the 20th century. Old phones can pile up in the home or be recycled for cash, traded in on another phone, and sent through a variety of recycling programs to recapture the valuable metals and materials they contain.
View More60 Minutes did a good story on where that ton of cell phones and other ewaste will end up in the recycling chain. There is a big difference between using thirdworld Chinese labor and ethical recycling as its done in Europe, Canada, and the US mostly. Edit Verbiage
View MoreBy recycling 1 million cell phones, more than 35,000 pounds of copper, 33 pounds of palladium, 772 pounds of silver, and 75 pounds of gold can be recovered. The excessive amount of lead in ewaste, if released into the environment, could cause severe damage to human blood and kidneys, as well as central and peripheral nervous systems.

View MoreBetween planned obsolescence, the sheer growth of interest in mobile phones, and the pace at which phones have evolved, electronic waste from phones is growing at an astounding rate. Recycling your phone helps to offset this trend and keep phones out of landfills where they essentially sit forever.
View MoreGold concentration in a phone is 50 times as great as it is in ore in a mine. Only 3 of the 1.8 billion phones expected to be purchased around the world this year will be recycled.
View MoreMobile phones are everywhere and many people cannot conduct their daytoday business without them. 205 million people in the USA alone use a cell phone. Millions of mobile phones are thrown away every day, and ewaste electronic waste is the worlds fastest growing waste material.
