I think it went ok, even though the tiny laptop keyboard ruined my typing test, though another gut who was there said he normally typed at 85wpm and the tiny keyboard dropped him down to 45, so there is that. Same guy used to work there before, took a contract elsewhere, and is now back reapplying, and he said the success rate is pretty high and I should be fine, so here's hoping. Good luck mate!

So yesterday Glencore announced coal extraction. reduction and then China restrictions kick in. Someone knew something.

Answering questions from a way back because I just spent three days traveling. A lot of people doing truck driving, operating etc directly on coal mines don't have a lot of transferable skills outside of mining. Some do indeed treat working on mines as a temporary money kick on their income and skill/study up while they pull down six figures for a few years looking to get out and back into the city once they are relatively set up financially. Lithium and nickle are exciting for the project builders but the scale of the ongoing business is just a fraction of what coal and iron ore are so the industry would shrink overall if coal or iron ore was to be eliminated. Another point I would like to make is that a lot of light manufacturing and technical support for mining is actually based in Australia (and hence employs people in Aus). It is mostly in support of the local industry but does export over the world, especially Africa, middle and SE Asia and a little into South America. I still think the industry overall would survive/contribute on the back of iron ore and coking coal (plus the rats and mice contributions of gold, lithium, nickel, etc) but I think it is under appreciated how good it is in Australia (relative to how it could be) due to foreign income from mining. I visit Aus occasionally and it always impresses me how much money is spent on quality of life improvements in the cities I have visited in the last five years - Perth, Sydney, Brisbane, Canberra and even Dubbo, Parkes, etc. Sure Canberra will always have awesome money spent on it but the sunshine coast never seemed to be a priority before. Why I said coking coal is because it seems a point that is missed surprisingly often - coking coal is irrelevant to the discussion of what can be done about climate change in as much as there is no feasible replacement. It is the reagent for making steel and nothing sensible has been suggested that can replace it or indeed steel. It makes that judges comments referring to climate change while upholding the NSW planning department decision (which was based on local considerations) a bit beside the point as the mine proposed was for coking coal. All that can be done to mitigate the damage of coking coal is to keep the quality as high as possible which Australia is the worlds producer of the highest quality.

Funnily enough the head of the QLD CFMMEU makes the same mistake in this interview. He carries on as though coking coal won't be mined and it kind of suggests that maybe Bill hasn't been saying much of use to this guy for some time. With the judge on the Gloucester ruling it was surely more about the opportunity to set the precedent. The wording seemed careful to place the "wrong place" aspect (too close to homes) ahead of the "wrong time" (worsens climate change) but still got it in there. Thanks for the insights, it's great. It's gonna be a nutty year hopefully watching coal die so post more.

I understood that coking coal was just very high purity carbon for turning Iron Ore into Pure Iron which you can make and do other ways but is not as cheap as pulling it out of the ground and then purifying?

hooman posted:Got a source on that one? What I remember of the process at the local steelworks is that you get your ore, you melt it in the furnace with coke, so that you get a nice mix with carbon in it, then you bubble oxygen through it in a different furnace until you've removed the right amount of carbon to get decent steel. Coke is coal which has had the crap baked out of it in a low oxygen environment, the carbon remains and all the other poo poo, poisons, tar, sulphurs etc gasses off. The purer the coal the less crud comes out when you coke it, and I'm assuming it's just not possible to coke the poorer grades of coal as you'd be drowning in poo poo and the remaining carbon would be spongey and wouldn't have good mechanical properties as is required for piling tons of it in a tall vertical furnace. There's a whole processing plant that goes along with the coking side of things collecting those byproducts or converting them into a usable form. Anyway in no part of the process do you get "pure iron", that stuffs just not useful. In the second furnace they're dumping in all kinds of additives and fluxes to get the right alloy for whatever purpose. The alternative method of arc furnacing your ore uses a carbon anode and I guess that's how the carbon gets in? It's been 10+ years and we didn't have an arc furnace here when I was at the steelworks. Stoca Zola fucked around with this message at 14:36 on Feb 21, 2019 |

Broadly speaking coal's there for 3 purposes in steel making - Heating the iron ore up - Sucking away all of the oxygen in the iron ore (by converting the carbon to CO2). - Adding carbon to the iron to make steel The third is kinda the least important. Coal makes up a few percent of the weight of steel but you need hundreds of kilos of coal because of the other two. And since you can recycle steel very efficiently that carbon isn't going into the atmosphere but is being trapped in some building somewhere. It's the second part that is the problem. You can use charcoal instead of coal but historically that has resulted in mass deforestation and was part of the reason we switched to coal anyway. There are experiments using hydrogen as a reducing agent (ie to suck up the oxygen) but that requires a lot of energy to perform electrolysis of water (splitting it into hydrogen and oxygen) or requires extracting hydrogen from natural gas.

hooman posted:Got a source on that one? It is not just carbon, as the coke is consumed it is oxidized to carbon monoxide which provides both the energy and the reducing environment for the iron ore to be reduced (via a high energy chemical reaction) to metallic iron. To replace it, you need to find something that provides 1,800+ degrees, a carbon monoxide environment and ideally flows counter current to the flow of gas as it is consumed for energy efficiency whist also introducing the minimal amount of other contaminants in a continuous process. Edit for spelling but also just for further explanation, carbon monoxide is important because it is one of the very few compounds that increases in affinity of oxygen as temperature rises - this is important as then you can heat something up enough such that the already chemically attached (to iron in iron ore Fe2O3) oxygen will react with the carbon monoxide in preference to the otherwise rather stable Fe2O3. For sources, any good secondary metallurgy handbook will have a good description of the process or I guess wiki should suffice.

Endman posted:This really begs the question - is there a sustainable future that can include large scale steel manufacture? Yes, because we don't need to eliminate all CO2 production, we just need to very substantially reduce it. There are certain industries and certain processes where it will be vastly more difficult to reduce CO2 output, but we can accept output from these industries if we have made savings elsewhere. There is no technological barrier to large scale roll out of renewables for electrical generation, electric cars, etc; the barriers here are political and economic. Long-haul aviation, shipping, some industrial processes, the barriers there are technological rather than social, but we can afford those areas if we make savings on the others.

I can understand needing a personal automobile if you live somewhere where public transport isn't an option, like a rural area. However, I do believe that the car can be almost totally eliminated from urban areas and replaced by god's own method of transportation. Rail.

They definitely need to improve standards of public transport. My observation of living in sydney and it really only being convenient to get to and from the CBD and not from any two other points in the city. My impressions of other cities in the world was that I could get somewhere without a car much easier. And the traffic also wasn't as bad.
