Natural Resources that shaped World History Copper Tin Iron Coal Oil South Africa
Natural Resources that shaped World History Copper Tin Iron Coal Oil Coal “self-sufficient in most of its mineral needs”, including . . . andalusite antimony asbestos chromium cobalt copper fluorspar lead lime limestone manganese nickel platinum phosphate rock silver sulfur titanium uranium vanadium vermiculite zinc zirconium South Africa
Natural Resources that shaped World History Coal reserves: 54 billion tons world’s 6th largest reserves provides 88% of S.A. primary energy provides 90% of S.A. electricity so why did S.A. build a nuclear power plant?? South Africa
SOUTH AFRICA • long way from coal fields to Cape area • more economical to build a nuclear • power station than to transport coal • 1984: plant completed/on-line coal fields major industrial areas
SOUTH AFRICA only 20 miles north of Cape Town WHY ? 1 - area is geologically stable spent fuel elements the only nuclear power plant in Africa low/intermediate level wastes
SOUTH AFRICA only 20 miles north of Cape Town WHY ? 1 - area is geologically stable 2 - cold water of the Atlantic Ocean is ideal for cooling 3- easily accessibility to national electric grid
SOUTH AFRICA “create an efficient regional electric supply” inaugurated in 1995 12 African countries 200 million people
SOUTH AFRICA DURING 2008 . . . . shortages/rolling black-outs THE FUTURE . . . . by 2012 $39 billion US new coal/gas turbine plants by 2025 . . . double total generating capacity . . . increase nuclear contribution from 6% to 25%
SOUTH AFRICA diamonds . . . Kimberly diamond mine nuclear power plant
SOUTH AFRICA diamonds . . . 1866: young boy found 21.25 carat diamond in a stream – called "Eureka“ 1871: 82 carat diamond found on slopes of nearby hill – GOLD RUSH Kimberley diamond mine Vail River Orange River 1882: claim map
SOUTH AFRICA KIMBERLITE PIPES – named for Kimberly, S.A. where they were first identified ground surface 1888: Cecil Rhodes consolidates leases into DeBeers Mining 1914: ‘Big Hole’ mining closes after - - 22.5 million tons earth moved - 6000 lbs diamonds found ‘underground mining’ continues - to depth of ~ 3 miles - closed in 2005 1882: claim map 2006: DeBeers/town open Theme Park & work toward ‘World Heritage’ site designation
SOUTH AFRICA 2006: DeBeers/town open Theme Park & work toward ‘World Heritage’ site designation
SOUTH AFRICA Buy gas, get groceries Ask for help Off she goes to a safe place! See sign about lost dog
SOUTH AFRICA gold . . . . Johannesburg gold, archeology Kimberley diamond mine Mine entry Tailings dump
SOUTH AFRICA gold . . . . Johannesburg gold, archeology Johannesburg historically, world’s largest producer 2007: surpassed by China
SOUTH AFRICA Gold Production History 1970 – 2/3 world production 2007 – 1/10 world production
SOUTH AFRICA Gold Production (million of ounces) South African mine have highest production costs 95% of mines are underground operations many mines are deeper than 1 mile declining grades of gold
SOUTH AFRICA Chris Hardnady (research/techincaldirector,Umvoto). . . . “. . . gold reserves 90% less than officially claimed . . .” “. . . reserves are only 3 times the 1970 production level . . .” (about 10 year supply at current production rates)
SOUTH AFRICA Challenges to South African gold . . . - royalties - increasing electrical charges - burden of BEE (black economic empowerm’t) - recent safety shutdowns - security costs - currency exchange fluctuations Opportunity . . . . . . . . - stronger future uranium market - possible re-opening closed gold mines where uranium Is present
SOUTH AFRICA So, how does geology impact our travels? Geologic processes create MINERALS . . . . . . . . . . . . COAL & URANIUM to fuel our factories & provide our electrical power . . . . . . . DIAMONDS & GOLD for industrial use & to adorn our bodies REMEMBER . . . . GEOLOGY ROCKS!
SOUTH AFRICA good-bye to the city . . . . . . and its dangers!
Next week – Session 6 Into the Bush . . . . Looking for Animals South Africa
Next week – Session 6 PLEASE! Return all borrowed books next week!
