Metallium, Inc: Rare, Exotic Metals and Elements for Sale
Calcium proved to be much more difficult to keep shiny while sealing it in its glass capsule. Partly for that reason, the glass capsule needed to be longer than the glass-encapsulated coins issued so far. The metal is very lightweight (lighter than magnesium). The method developed in sealing this metal is also used for Europium. Europium Nov. 2007

Calcium | Article about calcium by The Free Dictionary
Calcium is produced industrially by two methods: (1) by heating a briquetted mixture of CaO and powdered aluminum at 1200°C in a vacuum of 0.01-0.02 mm Hg; the calcium vapors, evolved according to the equation 6CaO + 2A1 = 3CaO ⋅ A1 2 O 3 + 3Ca, condense on a cold surface; (2) by electrolyzing a melt of CaCl 2 and KCl, using a liquid copper
Current status and challenges in developing nickel
Nickel (Ni) phytomining operations cultivate hyperaccumulator plants (‘metal crops’) on Ni-rich (ultramafic) soils, followed by harvesting and incineration of the biomass to produce a high-grade ‘bio-ore’ from which Ni metal or pure Ni salts are recovered. This review examines the current status, progress and challenges in the development of Ni phytomining agronomy since the first
