Question
Please Asnwer ALL
Thanks
1)List the three key principles of mineral processing (e.g., the “Three MinPro Commandments”). Explain why are these three rules so important to designing a comminution circuit?
2)Consider M. King Hubbert’s idea of ‘peak oil’. We have seen in lecture how these principles also apply to other fossil fuels (e.g., gas, coal, etc.). Consider a commodity such as nickel.
Do you believe that Hubert’s mathematical model would predict ‘peak nickel’?
Explain what this would mean to both the consumers and producers of nickel.
Would 'peak nickel' be any different from peak oil?
3) Consider the graphs shown. Which one shows a jaw crusher output and which one shows a ball mill output? To recieve full marks, EXPLAIN WHY you have made this choice.

1)The three main principles or three Minpro commandments are comminution,sizing and dewatering.These three are very important in designing the comminution circuit because the particles must be broken down into smaller pieces and must be properly sized in order to process the minerals.
2)Like in terms of peak oil,peak nickel can be expressed with mathematical model where when oil is present the volume is considered and when nickel is present the surface area covered by the component is also taken into account.
When the people and consumers are considered,people mainly use oil for domestic and commercial purpose while nickel is used only by consumers to produce power or any other mineral extract.
3)The first graph indicates ball mill output while the second graph indicates jaw crusher output because ball mills are used to crush particles with considerable size and so medium size is plotted in the graph while jaw crushers are used to crush down the particles to smaller size and hence %size passing is plotted.
