Industrialisation in south africa

Industrialisation in south africa

South Africa is unbelievably rich in minerals. Minerals like gold, diamonds, platinum and necessary basic metals like copper, tin, iron, lead and zinc make mining and the subsequent job creation, possible. The only other country with a similar variety of minerals and metals, is Russia.

the discovery of Gold and Diamonds in SA

By the middle of the nineteenth century Britain found the territories that she had colonized in South Africa to be an economical drawback. Droughts in the Cape Colony, fights in the Orange Free State with the Basutu, and weak rural markets in the old ZAR (Transvaal) made Britain decide to hand over the government of these territories by signing the Sand River Convention in 1852 with Transvaal and the Bloemfontein Convention in 1854 with the Orange Free State.

The discovering of gold in 1868 north of the Limpopo River, at first drew no attention, because in 1867 the first diamond was found near Hope Town. These alluvial diamonds were found in the silt near rivers. On both sides of the Vaal River more diamonds were found, which caused an influx of miners. The miners were unable to reach an agreement about their rights with President Pretorius, the leader of the OFS, and declared themselves an independent republic at Klipdrift.

During 1870 and 1871 diamonds were discovered further from the Vaal River, first at Dutoitspan (Kimberley) and later at Vooruitzicht. This became known as one of the biggest diamond discoveries in the world and miners from all over the world descended on the diamond fields. Conflict among the different claimants of the diamond bearing areas, the republics, colonies and tribal captains was unavoidable.

Although J.H. Davis had already discovered the first gold of the well-known Witwatersrand in 1852 on a farm near Krugersdorp, he was forced by the ZAR Government to keep quiet about it. Other gold discoveries were made, like the find by Walker and Harrison on the farm Langlaagte. Only in 1886 it became clear that this discovery was the important main reef of the Witwatersrand.

The town of Johannesburg developed on the farm Randjeslaagte. Transporters could no longer cope with taking people and goods to and from the mines, so railway lines were built. In 1892 Johannesburg was connected to Cape Town by rail; and in 1895 to Durban.

Activity 1:

Time-line exercise

[lo 1.2, 1.4, 1.5, 2.1, 2.2]

  • Draw a TIME-LINE on which you can show what happened on the South African diamond and gold fields that was discussed previously. Do it like this:

a) Write the words TIME-LINE and the topic of the time line, on top.

b) First ARRANGE the DATES in CHRONOLOGICAL ORDER.

c) Then WRITE down the DATES beneath one another.

d) Now FILL in the ACTIONS that corresponds to each date, next to the date. Make sure that every fact is complete.

Activity 2:

Source a and b

[lo 1.2, 1.3, 3.1, 3.3]

  • Read the following sources and then answer the questions:

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
