SELECTIVE EXTRACTIONS

Selective extractions using surface materials can be used to extract a specific component of the soil that may have been added by degassing biological activity or electrochemical cells.

Many ‘blind’ orebodies are buried beneath thick sequences of exotic overburden, lake beds, barren bedrock or younger volcanic rocks. Generally to be most effective at depth penetration, the weakest leaches are best including Bioleach and Enzyme Selective Extraction. Bioleach, a technology that Actlabs has developed, dissolves remnant proteins that bacteria have left behind when the die. These proteins migrate directly above mineral deposits by a variety of processes and bioleach is designed to digest this soil component which can then be analyzed by ICP-MS or for most effectiveness by high resultion ICP-MS.

Enzyme Selective Extraction (ESE) is one of the most discriminating of the selective analytical extractions in use today. This selective extraction targets amorphous mixed oxide coatings. By selectively removing the amorphous manganese dioxide from these coatings, the mixed oxide coatings collapse, releasing trapped trace elements. At this time, the greatest depth of penetration of ESE for a mineral deposit is greater than 800 meters.

The Enhanced ESE package offers lower detection limits than the standard package.

A 0.75g sample of -60 mesh B soil horizon material is leached in enzyme matrix containing a glucose oxidize solution at 30 o C for 1 hour. The enzyme reacts with amorphous MnO2 dissolving it. The metals are complexed with the gluconic acid present.

The solutions are analyzed on a Perkin Elmer ELAN 6000, 6100 or 9000 ICP/MS. For each tray of 54 samples there is one blank, three duplicates, 4 standards and 46 samples.

Bioleach uses technology proprietary to Actlabs, which dissolves remnant proteins that bacteria have left behind when the die. These proteins migrate directly above mineral deposits by a variety of processes and bioleach is designed to digest this soil component which can then be analyzed by ICP-MS

Through years of research by Actlabs, supported by CAMIRO (Canadian Mining Research Organization) with our SGH technology, it has been proven that microbiological processes are exceptionally important. Electrochemical Redox cells mobilize metals from the mineral deposit to the surface which become adsorbed on soil particles and create unique surficial conditions that bacteria then feed upon. Bioleach digests bacteria and their proteins from the collected surficial samples to analyze for the elements related to the blind mineralization.

A 0.75g sample of -80 mesh (or other mesh size of your choice) upper B soil horizon material is leached in proprietary matrix at 30 ° C for 1 hour. Two controls for every 49 samples are leached in the same procedure.

The solutions are analyzed on a Perkin Elmer ELAN 6000, 6100 or 9000 ICP/MS. One matrix blank is analyzed per 49 samples. Two controls are run at the beginning and end of the group of 49 samples. Duplicate samples are leached and run every 10 samples.

Sequential leaches can target specific soil or rock phases and allow a better interpretation of the geochemical processes involved. There is a static and dynamic approach to the leaching.

The static approach, a sample will undergo sequentially a leaching process starting with the weakest leach to the strongest leach with subsequent analysis of each of the leachates by ICP-MS.

The dynamic approach involves sequential leaching on a sample packed column on-line with one leach following the other in close succession and then graphically examining the leaches (costs are dependent on the required protocol and number of leaches).

Some of the potential leaches which can be combined sequentially include from the weakest to the strongest:
