Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • 99 wt% pure calcite with particles 45 mm has been produced by carbonation of wollastonite under mild conditions (10 bar, 100 °C).

    “Also, 99 wt% pure calcite with particles 45 mm have been produced by carbonation of wollastonite under mild conditions (10 bar, 100 1C).200”
  • Indirect processes, where cations are extracted in a separate step, may be suitable for controlling morphology and particle size of precipitated products for high-value applications compared to direct mineralisation.

    “Therefore, processes where cations are extracted from the feed material in a separate step (indirect processes) may be suitable for controlling the morphology and particle size of precipitated products for high-value applications, compared to direct mineralisation technologies. 200,201”
  • Indirect processes can generally separate silica, magnesium/calcium carbonate and iron hydroxides with purities as high as 90% by switching pH from acidic to basic.

    “t has been shown that indirect processes are generally able to separate silica, magnesium/calcium carbonate and iron hydroxides with purities as high as 90% by switching the pH of the solution from acidic to basic.10,72,200,202”
  • Separation of iron oxide before carbonation can enhance the quality of precipitated calcium carbonate produced from steel slag.

    “Despite this, the separation of iron oxide before the carbonation stage can enhance the quality of PCC produced by this method.200,201,213”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
