Charakterystyka mineralogiczno-chemiczna i surowcowa materiałów z hałd po kopalnictwie rud żelaza w rejonie częstochowskim
Abstract
Doggerskie rudy syderytowe w rejonie częstochowskim wydobywano nieprzerwanie od ponad 600 lat. Eksploatację zakończono w latach 80. obecnego stulecia. Wykształcenie rud, warunki geologiczne ich zalegania, a także metody pozyskiwania i przetwórstwa spowodowały powstawanie hałd. Pierwotnie gromadziły one odpady poeksploatacyjne a potem przeróbczo-przetwórcze. Materiały w nich zgromadzone można zaliczyć do kopalin towarzyszących i mineralnych surowców odpadowych. Jedne i drugie wykazują właściwości surowcowe predysponujące je do praktycznego wykorzystania. Wykonane badania zarówno o charakterze poznawczym, jak i utylitarnym w przypadku ponad 40 obiektów wskazują na takie możliwości. Będzie to wymagało potraktowania zwałów jako złóż antropogenicznych i spełnienia przez nie kryteriów wynikających z prawodawstwa geologiczno-górniczego. Na przeszkodzie temu może stać wymieszanie kopalin i odpadów w niektórych hałdach.
MINERALOGICAL-CHEMICAL AND TECHNOLOGICAL CHARACTERISTICS OF MINERAL MATTER FROM DUMPS AFTER MINING OFIRON ORES THE CZĘSTOCHOWA REGION (CENTRAL POLAND)
Summary
Siderite ores of the Dogger age had been mined without any break for more than 600 years, and their exploitation ceased in the 1980-ties. The development of the ores, their geological setting, as well as miningand extraction methods resulted in formation of numerous dumps. The material of the dumps was composed initially ofmining waste and then processing waste, and till now these accumulations have represented waste noxious for the environment. The waste disposed can be included into the categories of associated raw materials and mineral waste raw materials, both revealing technological properties that make them practically usable. This has been proved by fundamental and technological investigations, carried out on samples from more than 40 localities. To start the utilization of the dumps it will be necessary to categorize them as anthropogenic secondary deposits that should me et relevant criteria of the geological and mining law. The process can be hampered by the fact that same dumps are composed of unpredictable mixtures of usable and non-usable materials.
