POTASSIUM CHLORIDE (KCl) is a soluble salt that is an extremely efficient shale stabiliser when drilling hydro sensitive clays and shales. Inhibition is provided through ion exchange; the potassium ion enters between the individual clay platelets in the shale so that they are held together, thus eliminating entry of water from the drilling fluid.

Typically, salt cake contains aluminium nitrides and oxides, metals and salts (mainly potassium chloride (KCl) and sodium chloride (NaCl)). This by-product has to be cooled in-house to reach a safe temperature for transportation to salt recycling facilities.
Extensive experiments show that a reduced oxide content in KCl-NaCl-CaF2-slags lead to an increased aluminium recovery in recycling processes.
On the question "Safe and responsible disposal of aluminum chloride?", I would exercise more care (as to why, see chemistry below) as even neutralizing AlCl3 with NaHCO3 actually, in addition to CO2 and NaCl, may form insoluble aluminum carbonate albeit its apparently breaks down into aluminium hydroxide, if even formed.The latter, …
