1000 11m fraction are as shown in Table 3. The < 125 pm tailing fraction collectively contri-bute >50% to the extractable amount ofeach metal in the < 100a 11m fraction. CONCLUSION The copper tailings were a mixture of particles of sizes mainly < 1000)lID in diameter and the extractable heavy metal contents were higher in the finer particles.
Potential water recovery potentials for copper flotation tailings are shown in the below table. In Chile, current estimates for the cost of desalinated water pumped to the mine are as high as $5 per cubic meter or higher. Table 2: Potential Water Recovery for Dewatering Copper Flotation Tailings 
case for testing the possibility of leaching the copper tailings. The ore used,was a low grade copper tailing. The are is highly si1icous, which fact is favorable to leaching, as the Si02 does not interfere with the re actions between the copper in the ore and the solution. The screen analysis of the ore is as fol10ws;-On 80 mesh =

As copper tailings appear in ground form, the grading of copper tailings reported by Gupta and Thomas (2013) and Nitish et al. (2013) has a sizeable silt fraction of 0.06–0.002 mm. Copper tailings are considered to be finer than CS, which usually has a dominant sand fraction. Table 6.5 compares the geotechnical properties of copper tailings to those of CS, which have been reported in this ...

mine will be copper and molybdenum, estimations of copper tailings will be used. Approximations for the material properties will be made from previous research on copper mine tailings conducted by Bhanbhro (2014). The assumption c an be made that the mechanical properties will model material properties from other copper mines.
