The ability of plants to accumulate nickel was determined by Biological Concentration Factor (BCF) that was calculated as nickel concentration ratio of plant shoot to soil [13]. BCF value of 1 to 10 indicates hyperaccumulator plant, BCF values of 0.1 to 1 indicates moderate accumulator plant, BCF value of 0.01 to 0.1

From the plant to nickel ore. The plants are harvested and processed in order to recover the nickel they contain. The first step is combustion to concentrate the metal in the ashes and also to create energy. This energy can be used to heat buildings or generate electricity. As for the ashes, they are treated by hydrometallurgy to extract the

The corresponding nickel and cobalt concentrations in the produced leach liquor were 3.4 and 0.17 g/L, respectively. The value of the ratio Fe/Ni in the leach liquor was 10/1, much lower than the value 45/1 in the ore, thus showing the selectivity of the leaching of nickel over iron in the Greek ores by the above method.

Nickel, in low concentrations, fulfills a variety of essential roles in plants, bacteria, and fungi. Therefore, Ni deficiency produces an array of effects on growth and metabolism of plants, including reduced growth, and induction of senescence, leaf and meristem chlorosis, alterations in N metabolism, and reduced Fe uptake.
