Recovering metal values from geothermal brine - HARD; ROBERT A.
In general the amount of iron injected into the wellbore is in excess of that stoichiometrically needed to precipitate all of the lead copper silver gold and tin from the brine. This permits the residual part of the donor iron particles to be readily collected at the surface or wellhead using magnetic separation or a gravity separation

Basic care – Recognizing metals and their corrosion products
Uncorroded cast iron objects have a silvery-gray colour. Examples of cast iron objects include pots pans fire grates stoves cannons and cannon balls. The photograph on the left is a cast iron frying pan and the photograph on the right is a cast iron hand grenade. Photographs courtesy of the Canadian Conservation Institute.
Mine Tailings Tailings in Mining Gold Tailings Reprocessing
As for the gold tailings cyaniding prm will apply the method of dry-tailing stacking. That is though the process of classifying and dewatering at the same recycling the water recourses to remove the cyanide in it. Moreover prm will use magnetic separation and gravity separation to remove the iron.
China Separation Of Iron China Separation Of Iron
Water and ore will be fed from one end of the jigger screen the ore granules will move in the vertical alternative water-flows. Our machines are popular in separating GOLD copper manganes chrome tungsten tin nickel iron titanium lead zinc tantalum and some non-ferrous metals like quart zircon bariteect.
Chrome Processing PlantChrome Washing Plant -
Introduction:this technology is magnetic-gravity combined separation technology. Weak magnetic separation can hardly be separated with chrome minerals in coarse grains which leads an unideal gravity separation index. In order to recover high-grade chrome concentrates weak magnetic concentrates should be grinded.

Five Chrome Extraction Process to Teach you the Chromite Ore
Here are the common five chrome extraction processes. For the rich ore with high chromium oxide content single gravity separation or magnetic separation process can be adopted. For the chrome with low chromium oxide content the combined process of gravity separation and magnetic separation usually gets a better index than the single process.
Hematite Separation Process -
Magnetic separation sorts out the coarse concentrate and tailings and reduces the working of flotation operation. Strong magnetic separation and reverse flotation technology float little and inhibit much more cost saving. Strong magnetic process recycles fine iron minerals which can play a dual role of de-sprm and tailings out creating
