For low-grade iron ore dressing, the SS in process waters are highly dispersed during separation processes and difficult to completely remove—and this issue becomes serious with SS accumulation through process water reuse (Wang et al., 2019; Yenial and Bulut, 2017). SS removal from this process water form therefore needs more insight into the ...

After applying these modifications, the quality of the process water became acceptable for long-term reuse, and higher grade (65.10%) and recovery (68.50%) were achieved. The proposed flocculation method and the main conclusions from our work can provide information and advice for similar low-grade iron ore …

Water use in the Mining Industry •Generally, the majority of use is for mineral processing, smelting and refining applications. •Most of this is for flotation. •Use may be reduced by water management strategies, recycling process water, reducing evaporation, and seepage and dry stacking. •Another option might be the use of alternative

zinc ores is requiring about 6000 L/h of water for ore grinding and flotation (Jennett and Wixson 2005). This huge water demand has forced the majority of Chilean mining companies to treat and reuse their process wastewaters until complete quality deterioration before letting them to be ultimately stocked in ponds (Bosse et al. 2007).

to 11,300 gallons of water per ton of iron ore concentrate. Water use in con centration plants is related to the physical state of the ore. The data in this report indicate that grain size of the ore is the most important factor; the very fine grained taconite and jasper required the greatest amount of water. Reuse vas not widely practiced in ...

When chemical treatment is used, the water is generally reused in the mill; it may be passed through cooling towers, especially in the warm weather months. The recovered scale is sintered for use in the Blast furnace or open hearth furnaces. Mill scale is comparable to high grade iron ore and is thus a salvaged material of considerable value.

Minera del Norte – Cerro Del Mercado is an Iron ore mine in the north part of Mexico. Due the water scarcity in the region, usage of potable water was restricted and the mine was required to find an alternative water source for the production processes. Reuse of municipal wastewater of the nearby city was found as the most cost effective.

The resulting water can be reused in other manufacturing processes or released. ... In this process, ore fines and coal are manipulated to melt iron ore. In 1993, the process could produce eight tons of iron ore per hour using ore directly in the smelter. Process modifications are expected to increase the efficiency to 14 tons per hour.
