tailing dewatering screen is high efficiency in tailing treatment. the high wastewater content of tailings is one of the main areas of concerning for the mining industry now and mine operators are increasingly adopting all kinds of tailings disposal methods to minimize the impact of the tailings on the environment.
although many miners use mercury in artisanal and small-scale gold mining it is possible to safely and economically recover gold without it. mercury-free techniques are safer for miners their families and local communities. they may also help miners market their gold at higher prices.
sep 11 20140183;32;the gold and silver tailings were generated from conventional mining operations between 1992 and 1999. the original mining operation’s recoveries were poor (< 30%) and considerable amounts of ore were placed in the dam. the dam has an estimated 5137 million metric tonnes of ore grading 3.8 g/t gold and 38.6 g/t silver.
figure 2: simplified diagram showing the hydraulic re-mining of tailings. it can be noted that the use of hydraulic mining for tailings can be to either reprocess the waste mine the waste as a product or for moving of the tailings to a more suitable location.
drd gold extracted 33600 ounces of gold worth nearly us$40 million in the last quarter of 2013. mintails a mine tailings processor has developed new technology to process 350000 tons of slimes from its extensive tailings resources. it expects to recover 58 kg of gold per month and has enough slimes to last until 2025.
mine tailings' size and composition depends on the mining method. for hardrock metal mines tailings are usually a very fine mud or powder which is left over after ore is crushed and valuable minerals are extracted from it. tailings may also contain chemicals used for mineral extraction.
for example 99 tons of waste are generated per ton of copper with even higher ratios in gold miningbecause only 5.3 g of gold is extracted per ton of ore a ton of gold produces 200000 tons of tailings. (as time goes on and richer deposits are exhaustedand technology improves to permitthis number is going down to .5 g and less.)
summary: gold and silver hard rock mine; prior mining on parts of this property have yielded 2090 oz. of gold and 535 oz. of silver; projected total probable and possible gold and silver deposits worth almost $1.2 billion at $1200 gold and $16 silver based on a harrison western report

the evidence of past bucket-line dredging operations can be found in mining districts all throughout the west. these dredges were nothing like the modern suction dredge that we use today; bucket-line dredges were massive floating pieces of mining equipment that churned up the valley floors in many gold rich areas and processed the gravels.
