The iron tailings discharge from iron ore plant is in large amount, fine size and different types, and complex property, so Xinhai use the process of magnetic separation, flotation, acid leaching and flocculation to recover iron. Xinhai usually use all-slime cyanide process and carbon-in-pulp process to recover the gold from gold tailings

five gold tailings disposal methods to teach you how to

Oct 04, 2020 The gold content in the gold tailings is generally 0.2-0.6g/t. Due to the backward mining and processing technology in the past, a part of gold and silver was lost in the tailings. Meanwhile, most of the gold ores in China are associated with copper, lead, zinc, iron, sulfur and other elements

new carolin plans to capitalize on gold tailings near

Dec 07, 2020 New Carolin Gold (TSXV:LAD) (OTC:LADFF) today reported that recent metallurgical testing of samples from tailings at its Ladner project, located not far from Vancouver, B.C., confirmed that a significant gold concentrate could be produced by regrinding the tailings to a finer size and utilizing conventional flotation. The tests were performed by Met-Solve Laboratories of Langley, B.C., a full

gold tailings reprocessing technology

gold tailings reprocessing technology

The gangue minerals are mainly quartz, sericite, etc. The processing technology uses one-stage grinding, preferential flotation process. The gold and copper concentrate product can be recovered once. In general, the gold recovery method of gold tailings is mainly the all-slime cyanidation CIP method

modified-three-product column (3pc) flotation of copper

modified-three-product column (3pc) flotation of copper

Oct 01, 2011 The proposed circuit is simpler and more compact. The flotation of the fresh tailings recovered more than 40% of the copper losses and 25% of the gold losses at recyclable concentrate grades. The cleaning action of the 3PC cell is due to the selective separation of the froth drop-back, a low-grade material amenable for discard. Results are discussed in terms of their positive impact on the

copper gold sulfide ore - flotation & cyanidation tests

copper gold sulfide ore - flotation & cyanidation tests

Feb 16, 2021 The copper flotation tailings were cyanided for 4 hours; 28.9 percent of the total gold and 35.8 percent, of the total silver were extracted, giving overall recoveries of 91.2 percent of the Gold and 97.0 percent of the silver. Cyanide consumption was 4.7 pounds per ton of original ore

filtration of copper/gold tailings for mine backfill - bokela

filtration of copper/gold tailings for mine backfill - bokela

Amount. Two BoVac Disc filters L176 are operated in a Gold/Copper Mine in Bulgaria for the filtration of flotation tailings which are used for mine backfill. The dewatered and discharged filter cake is mixed with cement and pumped back to the underground to fill the galleries. For this special application the filtered tailings need to have a certain residual moisture to ensure constant conditions for pumping
