Bench scale testwork provides a raft of project design and operational criteria. However, the majority of green-fields projects will eventually need to undergo continuous piloting to ascertain the effect of recirculating streams and prove the process can reach, and sustain continuous equilibrium. Another important objective of a pilot plant is to produce product mass for further testwork and marketing purposes. These are critical project milestones and clients need a reliable provider with the necessary capability and expertise to deliver their projects to completion. ALS is that provider.
Industrial processing plants are engineered for purpose. Pilot plants are not, and thus the plant set up is intricate and requires great innovation to cater for sampling, low flowrates versus particle size distribution, and mismatching unit processes. ALS has a dedicated team of metallurgists and technicians who are expert in pilot operations. With one of the largest equipment inventories in the world, this capability has been proven over decades and hundreds of pilot campaigns, many of which have successfully gone on to construction and operation.
No. Our quotes are budget estimates, as are our schedules. Metallurgical testwork is not prescribed engineering. There are too many unknowns and variables to commit to lump sums. Our business approach, however, is to provide realistic, honest and transparent budgeting and any variations are always done in conjunction with the client prior to completion.
Yes. Provide with a finance commitment (i.e. PO) and we will reserve a spot in the queue, if there is one, otherwise we'll get right on it. Keep in mind that slot timings may vary due to unforeseen delays. ALS will always honor its commitments to existing programs.
Well...how long is a piece of string? Every pilot plant is different so we will need a scope of work to compile a quotation. Don't have a scope of work, no problem, we can help you define what we can do for you versus your needs. See next question.
Below is a list of questions we would likely ask in the case of limited information:
Generally, 200 mm top particle size. Any bigger than that and they won’t fit into our largest jaw crusher. In terms of mass, our blending room can handle 100 t lots at one time. Larger masses would need to be batch processed.
Generally, yes. ALS has facilities and procedures to treat fibrous and radioactive samples. Surcharges do apply, however, to cover safety equipment, monitoring and decontamination. /p>
ALS is a quarantine approved premises and treats many samples of oversea origin. Strict regulatory requirements are in needed around packaging and paperwork, however, ALS can advise you on these requirements.
Yes, clients are always welcome to visit our facilities and observe samples or tests in progress. Inductions are required and other rules may apply to visitors.
Yes, if a testwork program is in progress, ALS will happily dispatch testwork products and feed samples to vendors, third party laboratories, and customers as required. Fees apply.
Generally it is not required as the engineering around gold processing is so highly developed after many decades and the construction of hundreds of gold processing plants. Exceptions do arise, however, so contact us if you have an unusual requirement and will see what we can do to assist.
No, as it is not our core business and would put us in direct competition with many of our clients. We can, however, put you in contact with a range of reputable engineering providers and consultants.
