Constructing your Economics Mind

What kind of Mineral Economist are you?

• Policy v Scientism

• The meaning of Ideas v The meaning of Numbers

• Issues of the Individual v Issues of Society• Issues of the Individual v Issues of Society

• Unrelated v Interrelated

• Describe today v Prescribe tomorrow

• Macro v Micro

• K v L

Why we don’t get it!

There is a need to constantly update your thinking

You need to approach it analytically AND objectively!

THE PEOPLE SHALL SHARE IN THE COUNTRY'S WEALTH!

The national wealth of our country, the heritage of all South Africans, shall be restored to the people;

The mineral wealth beneath the soil, the banks and the monopoly industry shall be transferred to the ownership of the

MINERAL ECONOMIC POLICY

monopoly industry shall be transferred to the ownership of the people as a whole;

All other industry and trade shall be controlled to assist the well-being of the people;

All people shall have equal rights to trade where they choose, to manufacture and to enter all trades, crafts and professions.

Freedom Charter, 1955

Foreign shareholders currently only get around 3% of the value that mines produce. DM 2011

MINERAL ECONOMIC REALITY

•Mining production for June 2011 decreased 0,7% year-on-year, according to

data released by Statistics South Africa (StatsSA) on Thursday.

•Seasonally adjusted mining production in the second quarter of 2011 dropped

1,1%, compared to the first quarter of 2011.

•StatsSA says the main contributor the drop was a 2,7% decline in the

production of platinum group metals (PGMs), while iron ore production rose by

1,3%.

•However, actual mining production increased 7% in the second quarter of 2011.

Mining Charter

Revised Charter

•Mining companies must facilitate local beneficiation of mineral commodities by

adhering to the provision of Section 26 of the MPRDA and the mineral beneficiation

strategy.

• Mining companies can offset up to 11% of the value of beneficiation against the

ownership target.

•Aluminium smelter costs are energy dependant (30-50% of costs areenergy)

•When Trinidad was delivering at US$0.04 the smelters wanted it atUS$0.015

ALUMINIUM - CARIBBEAN

US$0.015

•Deal signed but then fell through. Later deals were secured.

•Benefit hoped for was (sidestream) industrial deepening and(downstream) broadening

•Net Value Add

•Maximise linkages

ALUMINIUM - CARIBBEAN

•Local technology development not just Operational and Maintenance involvement

•Need to develop two competing units (one private sector and one government owned)

•Preferred copper ore is the Cu-S family. Less popular is the Cu-OH family (e.g.malachite). Problem was large amounts of chrysocolla also recovered in mining.

•Volumes of oxidised ores keep increasing and processing is limited to economical extraction.

•Mass production of sulphuric acid enabled the processing of

COPPER – CENTRAL AFRICA

•Mass production of sulphuric acid enabled the processing of chrysocolla ore.

•This they called beneficiation!!

•Complex orebodies can now be exploited for local projects and longer process chains means that diversification can be considered.

•Decision to be made is does the SOE establish a new company to retreat the dumps, or should it give it to an existing market player…

Area Recommendation

Legal •Write the Beneficiation Act of South Africa

Beneficiation Strategy •Use evidence led analysis to inform implementation guidelines•Develop an interface between Policy and Analysis

Taxes and Subsidies •Use Pigovian Subsidies wherever Pigovian Taxes are imposedTaxes and Subsidies •Use Pigovian Subsidies wherever Pigovian Taxes are imposed

Employment •Make investment in Stage 2 and Stage 3 activities attractive

Costs •Provide SME support by removing Fixed Costs

Spatial Development •Declare coastal belt development nodes for specific commodities
