A gold processing plant in Inner Mongolia has a history of nearly forty years, which is a classical old processing plant. Before the new tailings pond construction completed in 2002, there are 90000 tons of tailings with

The resultant disgusting effect related to failure to produce environmental friendly tailing slurry, call for developing a good management plan for tailing slurry production of the
The three most feasible approaches to tailings management and utilization are: One is to cover the soil to create fields. In areas with sufficient soil, the method of
Gold mine tailings are wastes discharged from gold processing plant after the useful components are finely grinding from the large ore under certain technical
The results of the mineralogical examination of old sulphide and oxidized gold ore tailings of a mining and processing plant in the Krasnoyarsk Territory are presented. Secondary mineral forms of antimony, namely, antimony bloom Sb2O3 and tripuhyite FeSBO4, as well as iron are found. Gypsum in the waste is a newly formed phase,
Most mineral processing plants adopted lowlevel tailings management mode due to the limited economic level and ore beneficiation technology, which not only increased the amount of tailings discharge, but also caused mine resources waste. According to the preliminary investigation, the amount of gold tailing (gold grade was more than 2.5g/t
historic gold tailings dams in the Witwatersrand area of South Africa is being investigated. The objective is to recover uranium and residual gold from the tailings, as well as to oxidize the sulphides to eliminate long term environmental liabilities associated with acid mine drainage. The tailings from the reprocessing plant will be re
So, the regrind process was not considered in the recommended process flowsheet of the gold tailings retreatment plant. The recommended flowsheet sketched in Fig. 2 consisted of: feed classification, grinding the tailing to approximately −75 µm (80% −75 µm), bulk flotation, thickening of flotation concentrate followed by 24 h
Here, the material is pumped to a processing plant to extract the gold. This operation is much more costeffective compared to a truck and shovel operation, due to the use of slurry transport. However, the majority of the tailings are stored together with process water, which makes hydraulic monitoring of dry heaps impossible. Hence, the wet
3. Tailings reprocessing: At present, tailings are often accompanied by other valuable components, and the accumulation will cause environmental pollution and induce geological disasters. Among them, gold tailings processing can comprehensively recover valuable elements according to the properties of the tailings, which can improve the utilization
Xinhai usually use allslime cyanide process and carboninpulp process to recover the gold from gold tailings. As for the gold tailings cyaniding, xinhai will apply the method of drytailing stacking. That is, though the process of classifying and dewatering, at the same recycling the water recourses to remove the cyanide in it.
The processing capacity of the processing plant is 900t/d, and the output rate of cyanide tailing is about 3.8%, that is, the daily output of cyanide tailing is about 34.2t. The cyanide tailing gold grade is about 3.1g/t, the silver grade is about 34g/t, and the lead grade is about 3.5g/t. It can be estimated that the annual recovery of gold is
C—Volume of each cell in cu. ft. Long Tons of Solids: N = W x T/40 x C (R/L + 1/S) Short Tons of Solids: N = W x T/45 x C (R/L + 1/S) In the above formulas, no allowance is made for the degree of aeration
Tailings often contain trace elements such as Zn, Mn, Cu, Mo, V, B, Fe, and P, which are essential for maintaining plant growth and development. The tailings discharged by some dressing plants in Japan are alkaline. In the rice planting experiment, these tailings neutralize acidic soil and can improve the quality of acidic soil.
The gold tailings after cyanidation are dealt with tailings dry stacking method. It is a technology that recycles the filtrate to realize the water resources recycling in processing plants with pressure filtration process, and get rid of most cyanide in the tailings. For other elements in the gold tailings, Xinhai applies magnetic separation

At present, tailings processing methods generally have three directions: tailings reprocessing, tailings dewatering and tailings filling goaf. Later we will explain these three methods separately. 1. Tailings Reprocessing Method. Although the content of useful components in the tailings is relatively low, it can be recovered to a greater extent
Tailings dry discharge. It is a new process using dewatering type cyclone, highfrequency dewatering screen and highefficiency deep cone thickener. It can reduce the water content in tailings

Kat Gap boasts a 2.96 g/t gold grade and Classic’s “Gecko” processing plant is expected to recover about 96 per cent of the metal from ore. Two nearby deposits held by Classic are the target of expansion as the company seeks to grow its 59,700ounce Lady Ada and 250,000ounce Lady Magdalene deposits in the Forrestania gold belt.

Amongst these methods, cyanidation is the most common method used in the leaching of gold from the ore. This process involves the dissolution of gold containing ores in dilute cyanide solution in the presence of lime and oxygen. For refractory ores such as sulfide ores and carbonaceous ores which are not susceptible to direct cyanide leaching
