I do not wish to comment on the direction of this article but just to comment on the supply of sulphuric acid. As an chemical engineer I have knowledge and experience about sulphuric acid production. Australia has been self sufficient in the past and could be now without recovery of sulphur dioxide from oil processing. I have personally seen sulphuric acid recovery from smelting of zinc ores at Risdon Hobart Tasmania. The suphide ores are first roasted to drive off the sulphur using the heat of the slphur combustion. I know that sulphur dioxide was recovered at Mt Isa from the smelting of copper ores. Again the heat of burning the sulphur assists the heat from the combustion of coal or later natural gas. The sulphuric acid was used at Phosphate Hill near Mt Isa to make superphosphate where natural gas was used in the process to provide heat. There were metal smelters in Townsville Qld. (Cu & Ni), Port Kembla NSW (Cu) and Port Pirie SA. (Ag, Pb &Zn), and Kwinana WA. (Ni). Sulphur Dioxide has also been recovered from the coke making for steel smelting.

Australia should be a powerhouse of metal production and processing which is cheaper done here than transporting ore overseas. It is stupid unions and green socialists that shut down Australian industry for no benefit other than political control.

I as AI a question about the huge oil search deposits in north Qld. Not much information about the composition but it said that the Julia Creek deposit had 5% sulphur in the kerogen. Then it gave the following answer:- Retorting or hydrogenative processing

Convert the kerogen into shale oil, gas and char.

Sulphur would partition between the shale oil, product gas, char and mineral residue according to its chemical form and the process conditions.

Sulphur recovery

Oxidise sulphide or organically bound sulphur to sulphur dioxide.

Convert the sulphur dioxide catalytically to sulphuric acid.

The acid could be used internally for mineral processing or externally for fertiliser manufacture.

Processing the oil shale could fix all of Australia's needs in Petroleum , fertilisers and chemicals production. Have to get rid of the greens influence first.
