Background to the Nuclear Fuel Cycle •1939 – Discovery of fission of uranium by Hahn and Strassman in Germany with extra neutrons released gave rise to the possibility of a chain reaction. •1939–1942 – Concept of an atomic bomb was developed in UK, U.S., and Germany. •1942 – Start of the Manhattan Project and the need for the nuclear fuel
Ore processing is a 24 hour operation. Ore is stockpiled at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added to raise its pH. Following crushing through a jaw crusher, the ore is fed into the semi autogenous grinding (SAG) mill along with water and steel balls.
The required silver extraction process varies from the different mineral nature. The mineral extraction method usually used for independent silver ore centering on silver …

The findings showed that ultra-fine grinding can be used as a suitable and environmentally sound pre-treatment method to improve the extraction of silver from the refractory silver ore tailings.
The closest potential mill may be at the Silvertip project owned by Coeur Mining, which would entail a trucking distance of approximately 100 kilometers from Silver Hart.
the ore grade and the mass of ore to be mined and processed per kg recovered uranium. At a grade of 0.1% uranium, one megagram (1 Mg = 1 metric tonne) of rock has to be mined and processed to obtain 1 kg uranium in the mill. This is ten times as much as from rock at a grade of 1%, containing 10 kg uranium per Mg rock.
Ore fine crushing is a process of crushing ore blocks with a feeding particle size of 50–150 mm to 5–25 mm, and the maximum crushing ratio of fine crushing is about five. The main equipment suitable for fine crushing operations includes a fine crushing jaw crusher, short head cone crusher, high-pressure roller mill, etc. Ore superfine crushing.
