"Black sand mining" is also known as "iron sand mining", "dredging" or "seabed mining".Suction pipes (or buckets, an antiquated technique) going down to the seabed pump up the sand mixed with seawater, then the iron ore is separated magnetically. After that the sand runs over a system of sieves to further extract minerals.In an already approved exploration permit "garnet, gold, ironsands, iron, magnesium, rutile, titanium and zircon" have been mentioned. The worthless residue is pumped overboard and dumped.Because of the technical requirements, the mining – as the available maps show us – will take place in close proximity to the coast line. The depth for this kind of mining has to be between 25 and 70 meters of water – that means: very close to the coast and to the beaches.

Notice
This blog is no longer associated with KASM and while the url may still contain the word KASM it is not a KASM outlet.
I have decided against deleting the blog because it would not release the KASM acronym in the public domain as there is a KASM radio station in the US which has tried to monopolise all web extensions and many people have learned were to find it and might be interested in the dissemination of information about mining, fracking and drilling both internationally and in NZ as the asset sale John Key's National government program will be forced upon the NZ population
Here are three websites you might want to check out if you need to get in touch with KASM:
