- W2283392607 abstract "Gold mining is one of theimportant mining in Indonesia, besides the mining of coal, nickel, copper, etc. Gold mining in Pongkor (PTAntam) applied deep mining system. Besides producing gold as the main product, mining activity alsoproduces waste in the form of tailing obtained from its processing. Tailing is mining residue, whose gold andsilver contents have been extracted, and the tailing has somewhat inferior chemical properties if returned tonature as planting media. Organic matter and zeolite are known as ameliorant which may be used asmaterials for improving physical and chemical properties of tailings. The objectives of this research were tostudy the effects of zeolite and compost application on the chemical properties of tailing, growth of sengonplants, and absorption of lead (Pb) by plants. Zeolite with the dosages of 0%, 10%, 20% and 30%; andcompost with dosages of 0%, 10%, and 20% were added to tailings then used for planting seedling ofsengon (Paraserianthes falcataria L. Nielsen). The results showed that tailing from gold mining of Pongkorhad neutral pH values; high content of Ca and Pb; but very low CEC, organic-C, total- N, and bases otherthan Ca. Addition of zeolite and compost improve the chemical properties of tailing for growing plants.Zeolite had effect in increasing CEC, K and Ca; where as compost had effect in increasing all nutrientelements. Addition of zeolite and compost increased the height, diameter and crown width of sengon plantsobserved, although did not show significant effect (at α level of 5%), and was able to reduce Pb absorptionin root and plant crown." @default.
