Description of Laboratory Fees

The quoted laboratory testing rates are for the use of our facility, equipment, laboratory technicians and supporting personnel. The laboratory fees are charged either as a standard price (for Research Study), or at a daily rate (for Pilot Scale Development).

The Pilot Scale test is based upon a daily charge, plus expenses for optional processing equipment or materials. The daily charge is a minimum fee. The number of days quoted for your project includes estimated time for set up of the pelletizing system, for clean up upon the test completion, special pre- or post- treatment of materials or pellets (milling, mixing, drying etc.) and for preparation of the test report.

Daily, Overtime and Weekend Rates

The normal daily rate is for an eight (8) hour day, 7:30 AM to 3:30 PM, Monday through Friday. Time exceeding the normal workday will be invoiced at overtime rates. No overtime will be performed without written authorization by the customer.

Extraneous Supplies

Any special supplies needed for a test, and to be supplied by Mars Mineral, must be authorized by the customer in writing and will be invoiced at our cost plus 15%. All unused supplies will be returned to the customer upon completion of the test.

  • A completed Agglomeration Questionnaire (online or (PDF)

Mars Mineral policy requires that all materials shipped to us for testing will be returned to the customer. There are no exceptions. The materials will include unused raw materials, product, off spec material and clean up.

Arrangements for the return of the materials must be made prior to the test. All charges for the return of the material will be to the customer’s account and will be invoiced with the testing charges. To facilitate this, customers may provide their shipping account number on their secure, online Agglomeration Questionnaire (see Forms Required for Testing, above).

In the event that the testing is delayed or partially completed due to reasons beyond the control of Mars Mineral, the material will be held for a maximum of 30 days from the delay date.
