Material

Cínovec gypsum-method precipitated lithium carbonate, 96 per cent

The lithium carbonate precipitated from the condensed leach liquor, BEFORE water washing, reported by the source at 96 per cent Li2CO3. Held as its own material because the source characterises it separately from the washed product and this corpus does not combine two characterizations the source keeps apart.

What Lithoen records

Each claim states how it is known and cites its evidence.

EstablishedIdentity: Li2CO3, as zabuyelite by X-ray diffraction. This is a PHASE identification and carries no quantity; the amount of lithium carbonate present comes from the separately reported purity figure and not from the diffractogram. The washed product is this same solid after water washing, and the source reports its lithium carbonate content directly.

Measured at this deposit

The solid precipitated from the condensed leach liquor IS lithium carbonate, and this is established by the source rather than inferred from the chemistry of the precipitation: X-ray diffraction identifies it as ZABUYELITE, the mineral form of Li2CO3. The source also states that lithium was precipitated as Li2CO3 using potassium carbonate, and reports the solid's lithium carbonate content as a percentage — three independent statements of the same identity.

  • assertion basis: SUBJECT_MEASURED
  • method: X-ray diffraction of the lithium carbonate precipitate
  • sample material: The precipitated solid of one reported laboratory run

Establishedthe lithium carbonate precipitate before washing, as the source’s Table 3 reports it (AAS): K 1.1 mg/l, Ca 0.06 mg/l, Na 0.06 mg/l, Rb <0.1 mg/l, SO4 2- 1.86 mg/l

Measured at this deposit

For the precipitated product the source reports potassium 1.10, calcium 0.06, sodium 0.06, rubidium below 0.1 and sulfate 1.86, under the same 'Elemental concentration (mg/l)' header. The same unit problem applies: these are concentrations in a liquid and cannot be read as mass fractions of the solid.

  • assertion basis: SUBJECT_MEASURED
  • method: Not stated by the source for the impurity determinations.
  • sample material: The precipitated, unwashed lithium carbonate of one reported laboratory run of the gypsum method on a Cínovec zinnwaldite concentrate

Establishedthe lithium carbonate precipitate before washing: Li2CO3 96 %

Measured at this deposit

The precipitated product, before washing, contains 96 per cent lithium carbonate as printed in the source's Table 3. It is the LESS pure of the two products the source characterises.

  • assertion basis: SUBJECT_MEASURED
  • method: The source states no analytical method for the lithium carbonate content of either product.
