Cadmium is a chemical element with the symbol "Cd" and atomic number 48. It is a soft, bluish-white metal that belongs to the transition metals group in the periodic table. Discovered in 1817 by German chemist Friedrich Stromeyer, cadmium has since found various industrial applications despite its known toxicity. Sphalerite (marmatite, zinc ...

Lava rock, interesting. You ever try puttin em in Peroxide? I used lava rock this year smashed three yards by hand, and mixed the dust in. Lava rock is basalt, its pumice the beginning of pearlite, also interestingly enough a lot of silica your average basalt has 45-50% silica. I also use the montana silica thats harvested from volcanic duff.

Cadmium is particularly uniform, consistent with a homogeneous distribution in the mantle. Tellurium is more variable (1–6 ppb) and is notably higher in Loihi, ranging up to 29 ppb, the most likely explanation for which is accumulation of Cu-bearing sulfide.

It won't let me link the exact products to you, but if you search for basalt, rock dust, and azomite, you can find many examples of the most commonly used rock dusts and the results are a bit disturbing. They are variously high in cadmium, arsenic, and lead as well as other heavy metals that you might not really be concerned about, like nickel.

The rocks are dark-colored with no obvious post-magmatic alteration, and range from nephelinite through basanite to alkaline olivine basalt (Fig. 2b). According to total alkali contents (Na 2 O + K 2 O), these rocks are divided into strongly alkaline basalts and weakly alkaline basalts ( Wu and Liu, 2023 ; Yang and Liu, 2023 ).
