Environmental risks of abandoning a mining project already started: Romaltyn Mining Baia Mare

Abstract

Abstract. The history of mining activity, which has been the economy engine in the region and has contributed to the formation of many localities, has been deleted too quickly. During all this time, in the world countries which have invested in mining sector have made considerable progress. The paper brings in question, within the framework of the theme, the implications arising from the abandonment of the Romaltyn project which mainly affects two objectives: Central Tailing Pond and Aurul Tailing Pond. The Central tailing pond constitutes an unfortunate source of pollution for groundwater, surface water, soil and air on a large area around it, because its location upstream of Baia Mare city and in the vicinity of a agricultural production zone. The consequences of the tailing pond maintenance in the current situation are: presence of sclerozing dust with sulphurs content scattered over large agricultural area; soil pollution by acidification; heavy metals release which enter in food chain and will be found in food. The final disposal of the pollution source is the only solution really safe in long term. Abandoning Aurul tailing pond in the current phase of construction involves high environmental risks. Taking in consideration the potential and the huge soil volume which are necessary for rehabilitation, isolation and rehabilitation of this area involve extremely high costs and the realization is, technically, almost impossible in the current context.

A Deep Dive Into the Chronic Air Pollution Reality in Baia Mare: Part I: Sources of Historical Environmental Pollution in Baia Mare and Their Contribution to Air Pollution

“…Due to the long tradition in local mining and metallurgical activities, this is one of the country's most problematic regions in terms of historical pollution and related effects, and numerous studies were conducted here (Donisa et al, 2000;Culicov et al, 2002;Coman, 2006;Cordos et al, 2006;Cordos et al, 2007;Miclean et al, 2008;Damian et al, 2008;Levei et al, 2009;Damian et al, 2010;Modoi et al, 2010;Gurzau et al, 2012;Mihali et al, 2013;Chira et al, 2014;Dorotan et al, 2015;Bud et al, 2016).…”

Analysis of the possibilities of geometry of the Rosia Poieni mining field

“…As soon as the overburden is excavated, the material is removed and dumped. Modelling in 2D with the mechanical parameters of the rock suggest an analysis of the general open pit angle between 35° and 40° [3,4,[7][8][9][10].…”
