Agar sejalan dengan pemrosesan khas manusia, prosesnya harus mau berdamai dengan unsur-unsur bahasa yang tidak linear tanpa harus banyak melihat jauh ke depan (Levelt 1989). Jadi, setap komponen pemrosesan hanya bisa "melihat" bagian kecil saja dari proses yang sedang berlangsung dan tidak bisa "meliha" seluruh proses secara lengkap.
Theoretically, pure fluorspar (51.1% calcium and 48.9% fluorine) is colorless, but in the earth, the many different impurities found in the mined mineral imbue it with a variety of wonderful ...
Total reported U.S. fluorspar consumption increased by more than 9% in 2004 compared with that of 2003. Consumption of acid grade for HF and AlF 3 increased by 12% to 586,000 t, but consumption of fluorspar for metallurgical and other uses decreased by 7% (table 2). Acid-grade fluorspar was used primarily as a feedstock in the manufacture of HF.
