random notes, ideas

concrete channeling/fluid logic

- each heaps operate as extended noisy logic gates eg. stack materials allow different flows/ diversion of liquids or changes in mass and chained to next heap stack (stack frame heap relations played out)

eg. cement channels made with dilute sulphuric acid (studio tests) - return to earth, or buried → local collapses

eg channeling w. rock softening plants http://www.geopolymer.org/fichiers_pdf/CemPlant.pdf

- flows

  • collect leachates, poisons, toxic for
  • top down toxic flow
  • using resistant plates (stone, metal, plastic) to direct flows
  • allow mixing aeration and watering from heath/bog (eg. weak carbonic acid (rainwater) in pumps, mist sprays) (reaction w. pyrite && chalcopyrite > acid solutions of sulfuric, ferrous, ferric, and copper sulphates)
  • construct spiked elements as platforms for drying/residue flows
  • (residue tasting)

see also fluid logic but could simply imitate stack pull/push somehow: http://www.blikstein.com/paulo/projects/project_water.html

peltier-esque

- magnetic field generation incl. environmental peltier - ore layers (eg. manganese silicate) combined w. lightning or (much weaker) earth (telluric) batteries → thermo-emf ('cold spots')/cloud detector orig. peltier was bismuth/antimony and copper wires > small rock ore versionings > [cyano]bacteria added (differentials in temps)

bio-leaching

- bioleaching/biomining - chelating/sequestering heavy metals see http://www.pcbfab.com/waste-treatment/ - link w. algae/plants - mustard plants, alpine pennycress (Thlaspi caerulescens for nickel, zinc & cadmium etc, for uranium add citrate to soil (https://www.ars.usda.gov/is/AR/archive/jun00/soil0600.htm) - also see http://melchin.org/oeuvre/revival-field && https://en.wikipedia.org/wiki/Thlaspi), hemp, pigweed (see https://www.ars.usda.gov/is/AR/archive/jun00/soil0600.htm: “One species, a pigweed called Amaranthus retroflexus, was up to 40 times more effective than others tested in removing radiocesium from soil. We were able to remove 3 percent of the total amount in just one 3-month growing season” && https://en.wikipedia.org/wiki/Phytoremediation) - with fungi: Aspergillus niger, Penicillium simplicissimum

bacteria http://www.spaceship-earth.org/REM/Naeveke.htm

bacteria suppliers: http://www.ncimb.com/ (£200+) http://www.dsmz.de (200 euros+)

- Thiobacillus ferrooxidans (T. ferrooxidans) operate at 2 to 37 °C (growth rate incr. 50% every 6°C) - useful on low grade Pyrite, Chalcopyrite, Chalcocite, Sphalerite (source: http://etheses.bham.ac.uk/238/1/Jonglertjunya03PhD.pdf)

- Funghi of genera Aspergillus and Penicillium incl. the removal of silica from bauxite by using Bacillus mucilaginosus and Bacillus polymyxa, and the solubilisation of aluminum from alumino-silicates by Asperillus niger

heap leaching

general

- bio-sump - some kind of processing that outputs can be taken… not (necessarily) as cycling/oscillating process - filters can be diy 'rock' mixes

- stack micromorphologies - thin sections of stack/heaps for eg. petrographic microscopy (Leuphana Geology Dept.) - finer resolution of human interventions - framing indeterminancy

- Lüneburger Heide (Heath): juniper, agriculture, hilltops (100m+), lightning

- growing plants in free silicon

- http://ancient-origins.net/ancient-places-asia/mysterious-gobekli-tepe-inturkey-00186 stones set out then buried

Testing/analysis

refining/precipitation:

- bicycle wheel centrifuge

- diy retorts eg. pyrex bowl

- bucket test leaches:

  • 1 pt. sodium hyperchlorite (bleach) and 2 pts. Hcl (33%) > submerge (gold) stock/ore > gold(III) chloride (opt. > precipitate with sodium metabisulphate in water (= sodium bisulphate), leave until brown powder settles, etc)

stack frame heap:

  • stack is push/pull when we call a function
  • frame (frame stack or stack frame) can be storage for meta-information (eg. stack pointer) or is frame in stack
  • heap is for temporary strings, lists

eg. http://net.pku.edu.cn/~course/cs101/2008/resource/heapAndStack.html

see: matte (1st stage pre-metal refining), metal (refined), slag (waste/heap leach) - mix of push (crush material int smaller bits) && pull (extract) techniques

heap leaching

for oxide/sulphide ores

  • natural - rainwater (weak carbonic acid) percolation && precipitation (eg. iron oxide, calcium sulphate, ferrous sulphate)(along with enzyme/cyanobacteria actvity) - eg. pyrites/copper sulphide minerals piled in open air and left exposed over months to rain/air provokes oxidation and dissolution of copper.
  • ferric sulphate 1,2,10g/l eg. over chalcopyrite
  • sulphuric acid - 5% chalcopyrite to sulphuric acid (w/v)(eg. 25g/500ml)
