Amalgam obtained by either process was then heated in a distillation retort, recovering the mercury for reuse and leaving behind the gold. As this released mercury vapors to the atmosphere, the process could induce adverse health effects and long term pollution.
Scientific Consulting Laboratories, Inc., was retained and funded by Mercury Treatment Alternatives, Inc., the predecessor company of SepraDyne Corporation, to develop the high vacuum indirectly-heated rotary retort technology.
BEST ANSWER: I have used vacuum pods and other vacuum clamps in the past.They all have a flexible gasket to seal the vacuum against the bottom of the work piece. I had to put thin shims in the get the parts being clamped to be "bottomed out" to get a reliable Z0 position. Also consider that for large work pieces, the piece itself with bend down toward the table with any Z force at all.
Inches of mercury or inHg is a non-SI unit for pressure. It is still widely used for barometric pressure in weather reports and aviation in the United States, but is considered somewhat outdated elsewhere. It is defined as the pressure exerted by a column of mercury of 1 inch in height at 32 °F (0 °C) at the standard acceleration of gravity.

It is filtered through a special 1mu Oro Mercury pressure filter, where the liquid Mercury is separated from the Gold amalgam. The Gold amalgam is 50/50 by weight Gold & Mercury. The amalgam is then placed into a Oro Mercury Retort, where the Mercury is safely retorted (vaporized) and re-condensed into a clean gold free liquid.
When the retort program is started several events occur. The events are described as follows: Vacuum. Vacuum systems start and are controlled to generally 30.5 to 45.7 cm (12 to 18″) Hg at the receiver. Vacuum valves are then opened to the condenser/retort evacuating any air and gasses through the carbon filter canister.
Designed to protect closed vessels and piping systems against collapse when the induced vacuum exceeds design conditions. When used on steam heating systems, the No. 26 Vacuum Breaker controls induced vacuum, permitting normal return of condensate to the boiler. Adjustable range 1/4″ to 20″ (mercury) vacuum. Factory set to 4″.
• Mercury must be stored in containers that are not made from Aluminium and must close very tightly. • Put a layer of water over the Mercury to lower the vapours (unless it is charged Mercury). • Avoid spilling Mercury as it shatters into tiny particles that are almost impossible to find and clean up.
Metallurgical ContentMinimize Mercury LossesProperties and Purification of MercuryTypes of AmalgamHow to Purify Mercury The solid amalgam, which is retained in the canvas or wash-leather filters, usually contains from 30 to 45 per cent, of gold and silver, according to the state of division of the gold present in the ore, and also to the degree of care exercised in squeezing …
The holes between the wires were about 5 cm x 5 cm. The retort had no mercury in glass thermometer. The retort is cascading water (spray) type, in which the heating medium was hot water. The water distribution system was located at the top of the retort to allow heating and cooling water to cascade (rain down) over the containers.
EnviroCare’s Mercury Retort Furnace is designed to thermally vaporize water, mercury and zinc present in gold ore precipitates. The thermal energy required is provided by electrically heating the concentrate. By means of a vacuum, the mercury vapor is drawn through a water-cooled condenser where the vapors become liquid and are collected and sold to the commercial market.
