Here are a few options for the Swedish translation, ranging from most direct to slightly more journalistic:

Option 1 (Direct translation):

”Guldgruva i Centralafrikanska republiken beordras stängd efter dödligt ras”

Option 2 (More concise/headline style):

”Efter dödligt ras: Guldgruva i Centralafrikanska republiken stängs”

Option 3 (Slightly more dramatic):

”Dödligt ras i guldgruva – Centralafrikanska republiken beordrar stängning”

Option 1 is the most accurate translation of your original phrasing. Option 2 is punchier and typical for Swedish news headlines (using the colon). Option 3 uses a dash structure, which is also very common in Swedish tabloid-style headlines.
