Alumina factory

Hello i create alumina factory with recipe to dont make silica and i have setup with 4 pairs of rafinerys who can create 2720 alumina scrap so my setup looks like two rafinerys sending water back to another 2 rafinery who make alumina solution so that two raf. Sending back 2120 water and from water pump i send 160 one need another 80 to one to fill up to 200 what i need , on pipes i using valves offcourse but that setup never work to 100% cause still some water missing what is the problem that setup use max 400 from 600 capacity of pipes so pipe bug who never use it for 100%of pipe here no influence. And if i send more water that setup stop work cause pipes are full and cant take water back from rafinery. Some ideas how to solve this?

Pink alumina ball, one of a number found in the South Island of New Zealand. This one seemingly fell from the sky in 1978. Heavy at 99.7gm, length 42mm, been to a ceramics conference in Tokyo, spoken to a NASA scientist, some 40+ years later still don’t know what it is. reddit.com/gallery/p3jy8d

Sloppy Alumina + Electrode Aluminum scrap loop

For aluminum refining I like to put my alumina and scrap refiners on top of each other. The sloppy alumina is refined underneath and the scrap is refined on top.

The bottom refinery pumps the alumina solution to the upper layer using a vertically positioned pipeline junction cross (build horizontal pipe, place pipeline junction cross and rotate it vertically, delete horizontal pipe, feed fluid into the bottom of the cross and it is forced out the top with extra head lift).

I built the pipeline junction at the bottom of the alumina pipe first, then connected it to the two refineries

The water that comes out of the top refiner gets fed back into the bottom one. I ended up doing something a little weird with the pipes to get it to work, but basically it consumes the water coming from the higher elevation before accepting more water from the nearby water pumps.

I then feed the aluminum scrap into a stack of smelters to make pure aluminum ingots.

Each layer has 3 smelters

The water situation with alumina production is making me insane.

This has easily been the most frustrating thing ever for someone that likes to keep a factory running smoothly. I have all the numbers worked out so that the water pumps and the leftover water from making scrap add up correctly to the amount of water needed to produce alumina...

...BUT the problem is, sometimes machines slightly over produce or underproduce and shut off briefly, and any time this happens, the pumps keep running even though other stuff is shut down, and water slowly accumulates until it fills up and has to be dumped out manually...

Has anyone figured out a system to dump out water but only after it reaches a certain amount? I was thinking about trying to move over some plastic, package it, and dump it in a sink, but only if it ends up being too much (otherwise I could just scale down the water pumps slightly)

Edit: I just noticed, I think the train depots lock up when the train is loading and unloading, even if they have space, because every time the train pulls up, the refineries fill up and halt after a moment... and stop consuming waters, and the pumps keep making water pile up.

Efficiency of Alumina Setups

I read a couple of analysis on the alternates and came up with a couple of questions. I always use electrode scrap for my calculation.

If I use basic alumina solution, I get 1,5 Scrap and 0,17 quartz ore (with cheap silica) per 1 bauxite ore.If I use sloppy alumina solution, I get 1.8 Scrap per bauxite.If I use the blender recipe however, I use 1/3 Sulfur per Bauxite, but gain 2 scrap.

All these resources are quite rare and limited, so for a lategame optimised build that only cares about resource efficiency:

Is 1/3 Sulfur per bauxite worth the sulfur as tradeoff for 0.2 more scrap?Is gaining 0.17 quartz worth losing 0.3 scrap?

And concerning smelting the scrap: Is 0,35 Quartz worth gaining 0,5 more aluminum ingots?

High Purity Alumina Market tSize 2026 – Global Industry Sales, Revenue, Price trends and More

The GlobalΒ high purity alumina marketΒ is expected to reachΒ USD 7.20 billion by 2026Β according to a new study published by Polaris Market Research.

The global high purity alumina market has been divided based on purity level, application, and technology. Considering the purity level, the market is classified into 4N, 5N, and 6N. It is the 4N level of purity held the largest market share in the market followed by 5N and 6N. The enormous application of the lithium-ion batteries where the 4N purity level of alumina is maintained has resulted in the segment holding the largest market share of more than 40% and will continue to maintain its dominance in the forecast period of 2018-2026.

On the basis of application, the high purity alumina market comprises of semiconductors, sapphire, phosphorus, and electronic display among others. Here the electronic display held the largest market share which can be contributed to the huge demand for LED-based electronics globally. Moreover, the LED is more environment-friendly and sustainable that has led to the government pushing the application of LED making it one if the fastest growing technology globally.

The market for high purity alumina is also bifurcated by technology into hydrolysis, and HCL based. It is the hydrolysis segment that held the largest market share because of its feasibility and lower operational cost. The HCL based technology still is at a nascent stage and needs more time to get commercialized.

A few major driving factors for the high purity alumina market are growing demand for high-resolution electronics like television and smartphones that use high purity alumina for better display. Moreover, the rise in demand for smart wearables and other technological devices that uses LED is further having a positive impact and driving the market for high purity alumina globally. Among the regions, Asia-Pacific is expected to hold the largest market share in the global high purity alumina market over the forecast period of 2018-2026, followed by North America and Europe.

DYI alumina smelter?

( DIY alumina smelter ) should be title.

Imagine the increase of available metal if you could separate the oxygen from aluminum from your slag! I realize that prevention (flux) is far more practical but you will still end up with some loss.

I know that in industry they use electrolysis with a carbon anode to create CO2, removing the O2. Electrolysis isn't inherently difficult and graphite anodes are easily available. So I'm a little surprised someone has setup a DIY smelter. I suspect there is a fair amount I'm missing though.

Thoughts?
