In this paper we discuss the Herndon hypothesis that a nuclear reactor is operating at the center of the Earth. Recent experimental evidence shows that some uranium can have partitioned into the core. There is no viable mechanism for the small amount

During the production of natural gas from Dutch Rotliegend and Kupferschiefer sediments, next to "conventional" carbonate and sulphate scales, sometimes also lead deposits are formed. These deposits, which vary in composition from galena (lead sulphi

Mimicking geochemical processes to solve environmental problems was implemented in dealing with waste acidic jarosite and alkaline coal fly ash. By placing these two chemically different materials adjacent to one another, a self-sealing layer was for

Recently, precipitates of metallic Pb and galena in gas production facilities have been reported to contain 210 Pb. In the North Sea area, U-bearing Kupferschiefer or Carboniferous coal measures have been suggested as a possible source of 210 Pb. Thr

Jarosite waste, originating from the zinc industry using hydrometallurgical processing routes, is considered hazardous. Metals such as zinc, cadmium and copper are present in an environmentally mobile form, thus the jarosite waste is usually stored i

Copper is widely used in electricity wire and electronic devices, which makes it one of the most important base metals. Hydrometallurgical processing routes are typical for ores with low copper content. The low-grade copper ores are stacked in large

Municipal solid waste incinerator (MSWI) bottom ash is predominantly composed of high temperature solids. In a natural atmospheric environment many of these solids are metastable and will alter to form thermodynamically stable assemblages of minerals

Autoclaves are closed vessels in which liquids can be heated above their `normal' boiling points. As a consequence the pressure will rise. This equipment has permitted a variety of processes like the syntheses of organics and the leaching of metal or
