For example, a ball mill containing quartz cobbles can be used for smaller samples. For large scale use, a commercial grinder can be used, e.g. Buffalo Steel Mill Company (Buffalo, N.Y.). Prior to mixing the SPC and mercury containing waste, the reaction vessel is placed under an inert atmosphere such as argon or nitrogen.

: S+C cathode material was prepared by simple solid-state reaction in ball mill. Content of sulphur was approximately 80 wt. % in final sample. Cyclic voltammetry and galvanostatic charge/discharge techniques were used for characterization of the samples. Initial discharge capaci-ty observed for S+C sample was 600 mAh/g. sulfur

To ensure the full interaction of mercury with sulfur, it is necessary to constantly update the contact areas of the reacting phases, which in the experiments was provided either by manual grinding of the reaction mass in a mortar or by grinding the reaction mass in a …

Sulfur Polymer Cement was provided by Martin Resources (Odessa, TX). Initial studies used SPC that was ground in a ball mill containing quartz cobbles. The resulting powder was separated using a 60-mesh sieve. For larger scale studies, the Buffalo Steel Mill Company (Buffalo, NY) was contracted to grind the SPC to a fine powder. The

from liquid mercury and elemental sulfur using the mechanical energy provided by a ball mill in different conditions. Metacinnabar formation was observed even after short milling times (15 min) and unreacted liquid mercury was no longer detected after 60 min of milling. The reaction mechanism was monitored with a

In this study using 2,400 mL pots with balls of 19.04 mm diameter, the maximum capacity (1152 g-Hg/h/pot) was equivalent to the value calculated by extrapolating the results from previous laboratory-scale experiments. Ball size was the most important parameter studied under various conditions. As the ball diameter increased, the stabilization ...

The mercury metal waste of 121 g and sulfur powder of 21 g were mixed using a planetary ball mill under 400 rpm for 20 min to proceed the stabilization reaction to metacinnabar (HgS). ...

Elemental mercury and sulfur were mixed using planetary ball milling under various experimental conditions and the optimal conditions were determined. The labile intermediate, mercury sulfide, was observed in the early stages of milling, and the intermediates were then pulverized into mercury sulfide powder.

within the European LIFE program as a long-term storage option for mercury. This process leads to the obtainment of a stable concrete-like sulfur matrix that allows the immobilization of mercury. The final product, in the form of a solid block containing up to 30 % Hg, exhibits excellent mechanical properties (compressive strength 53-61MPa

With the application of mechanical energy provided by a ball mill to a mixture of liquid mercury and elemental sulfur it is possible to obtain mercuric sulfide in the form of black metacinnabar powder. Excess sulfur above the stoichiometric value favors the reaction efficiency and lowers the temperature inside the milling jar.

The reaction mechanism was monitored with a scanning electron microscope. The impact and friction forces of milling on the Hg and S mixture resulted in the formation of metacinnabar by reducing the size of mercury drops, giving rise to microspheres, and lowering the surface tension to allow sulfur grains to become adhered at the reaction interface.

This indicates that the movement of the balls in the grinding jar causes the massive fracture of liquid mercury into microspheres, and thus increases the surface area available to react with the sulfur. The formation of an interface between the Hg microspheres and the sulfur leads to the reaction and formation of HgS (metacinnabar).

The solid-phase reaction of mercury from sulfur carried out in ball or vibration mills, is proposed to use. The article presents an original technological scheme.
