· Reduction of tailings moisture and intelligent transportation system to the dump. on the clay and/or fine particles content. After passing through the primary crusher, the ores are sent to the stock pile from where the secondary crushing plant is fed in variable proportions to obtain the copper grade. required by the process.
discharge radius has not limited the capacity. In mature fine tailings, MFT the demand is to achieve a dry cake and still operate at a high solids load (tonne/h). In order to capture the fine particles in MFT we need to add polymer. This will give solids with a cake like .
Gold Tailings: 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.
After settling and selfweight consolidation, the dry density of the undesiced tailings is a function of the G s of the tailings solids. For coal tailings, the dry density is about t/m 3 due to their low G s, while for metalliferous tailings the dry density is up to t/m 3 due to their higher G s. Figures (a) and (b) show typical wet and dry density and w profiles with depth for ...
Iron tailings: 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. Gold tailings: Xinhai usually use allslime cyanide process and carboninpulp process to recover the gold from gold tailings.

Tailings ReProcessing LineXinhai [Process Introduction] Iron tailings: 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.
The tailings from the screen fall into a CP10 Vincent press. Previous to purchasing the screw press, the mine was using a centrifuge to remove water. This reduced the mica to a 35% moisture content. Since there is some sand left with the mica, heavy abrasion resulted in severe maintenance costs.

Mining Waste Products. The types of waste materials generated are dependant upon the type of mining activity. Around the Fal Estuary there have been effectively three main types of mining activity: (1) the recovery of cassiterite from the river sediments (so called tin streaming or placer mining); (2) the underground and opencast mining for metal (hard rock mining); and (3) opencast mining for ...

the discharge rate, the discharge duration, the permeability of the deposited tailings, its degree of saturation, the presence of retraction cracks, the position of the phreatic level (Zandarín et al., 2009). Moreover, the deposited tailings form a beach gently sloping towards the decant pond (usually layer slop is .

tailings discharge of dry", in which it was formalized that there must be a dam to store the filtered tailings, especially in SRRC. By storing the filtered tailings instead of the tailings slurry in a dam, the filtered tailings storage facility (FTSF) has been the safest and most environmentally friendly tailings disposal method in SRRC ...
