1. GEOLOGY, MINING, AND MARKETING OF THE INDUSTRIAL MINERALS Virginia McLemore and James Barker

2. What are industrial minerals?

3. any rock, mineral, or other naturally occurring material of economic value, excluding metals and energy minerals.

4. Why are industrial minerals so important?

5. Because your world is made of them

6. Why are industrial minerals so important? the average American uses about one million pounds of industrial minerals, such as limestone, clay, and aggregate, over the period of a lifetime.

7. U.S. flow of raw materials by weight 1900-2000. The use of raw materials in the U.S. increased dramatically during the last 100 years (from Wagner, 2002).

8. Two categories bulk rocks –aggregate –production of lime –ceramics –portland cement ore minerals

9. Construction limestone dimension stone (granite, marble, flagstone, etc.) clay diatomite perlite gypsum lime

10. Metallurgical Bauxite Silica Quartz Dolomite Magnesite Garnet Iron oxide Barite Pumice Graphite Asbestos

11. Chemicals Barite Dolomite Lithium Magnesite Phosphates Bauxite Limestone Pumice Borates Zeolite

12. Agricultural Phosphates Borates Clays Perlite Dolomite Talc Vermiculite Peat

13. Glass and ceramics Borates Silica Quartz Soda ash Kaolin Pyrophyllite Talc Bauxite Alumina

14. Fillers and extenders Barite Clays Soda ash Diatomite Titanium minerals Gypsum Limestone

15. Energy Clays Magnesite Graphite Lithium Drilling mud Refining additives Batteries

16. Environmental Bauxite Alumina Dolomite Limestone Zeolite Asbestos Perlite Magnesia Gypsum Pyrophyllite

17. Other uses Clays Dolomite Talc Magnesite Limestone magnesia Zeolites Nitrates Potash Salt Pharmaceuticals Drugs Cosmetics Food additives

18. “ Without a market, an industrial mineral deposit is merely a geological curiosity” Demand feeds back from the end-use market, to the end product, to the intermediate end product, and finally back to the mineral supplier.

19. Geologically, most industrial minerals are widespread have enormous reserves are easy accessible

20. Economically development needs less investments are cheaper to obtain –must be closer to the market –some specialty minerals demand a higher market price than metals are more effective

21. Technologically needs less processing needs less energy less effect on the environment possess exceptionally attractive properties for the industry

22. Class The class will meet one day per week for 90-180 minutes Remaining time spent on field trips or in occasional extra discussion sessions (SME meetings, other presentations) Gives time for the presentations and project

23. Textbooks Carr, D. D., ed., Industrial Minerals and Rocks, 6th edition: Society for Mining, Metallurgy, and Exploration, Littleton, Colorado  available online from SME at student price ~$80 if you become a member online (use Barker member #0154600 as recommendation) to get this price (save more $ than membership costs plus you should all be members of SME anyway) Barksdale, R. D., ed., The Aggregate Handbook: National Stone Association, Washington, DC  available from National Stone Association online for ~$15 to students

24. Specifics Exams: Midterm and Final—both are take home exams that will emphasize short answer and essay questions written in bluebooks. Term project—you are required to do a research project that will involve some original work. I will give you use of my telephone for long distance calls if necessary. Field trips—there will be 2 or more field trips and a group report on each trip will be required.
