Walter G. Steblez, The mineral industries of Albania… (2000)
“ Under the central economic planning system, especially from the late 1970s through 1990, Albania's chromite mining operations were among the more important components of the mineral industry. During this period, Albania was a leading world producer and exporter of chromite; the country often was ranked second in terms of export and third in terms of production. During this period, exports of chromite, ferrochromium, and petroleum refinery products constituted the country's chief sources of foreign exchange. ”
