It is common practice for mines to store tailings waste as a fluid slurry behind earthen embankments or in
depleted mine pits. Looked at purely from an upfront cost perspective, this is generally the most economical
option. However, look at the same facility long-term and it is a different story. Unless mine owners view
tailings management from a total cost/benefit perspective from cradle to grave, their risk analysis of what is
considered an appropriate tailings management solution for start-up could be very short-sighted.
A dewatering approach that extracts most of the liquid and changes tailings from a fluid to a soil product,
offers many mine sites substantial long-term benefits

I think it is missing a link? Is it this one? DOI

After reading it, I wonder if there are studies out there researching whether forbidden cakes are easier to bio/phytoremediate compared to forbidden slurries

Yes that's it thanks. I was having trouble trying to link direct to the document
