This largely depends on the conventions of the academic field and/or the publisher’s stylesheet.
In some fields, the standard practice is to have a separate citation for every point that is based on an outside source, even when several such points, all taken from the same source, appear close to each other. If one is following such a practice in combination with the footnote/endnote method of citation, each citation would have its own number, with the first note providing the full bibliographical data, and the following ones using some abbreviated format (or ibid. if that is customary in the field).
In some other fields, it is generally acceptable to have a single citation at the end of a lengthy sentence or a group of sentences that are all based on the same source. Use of this method, however, requires that the writer be careful to present the materials in such a way that it will be obvious to the reader what the citation applies to.
The only advice that can be given to the OP is then to look at how other published materials in the same academic field, and in particular in the same academic journal, deal with this matter, and then follow their example. Also, whenever one is in doubt about whether one should cite, it is better to cite than not to cite: underciting may be regarded as a serious fault, while overciting is, at worst, a minor stylistic infelicity, which may be corrected by the copyeditor.
(Incidentally, the example in the question is somewhat confusing, because its second part is not presented as a quotation, and yet the beginning of the question refers only to quotations and does not mention paraphrases.)
