“…In essence, the adequate amount of quartz sand and feldspar was crucial for higher flexural strength, at 476.8 kg/cm 2 as performed in the composition 2. Even though the flexural strength of the three different composition was fluctuating, those all values are still in the range of acceptable flexural strength for whiteware [17], [18]. The kaolin also has an important role especially in maintaining creep resistance in conventional ceramics.…”

Purpose. To do experimental research into the potential utilization of residual quartz-based sands and kaolin from the tin mine tailings in Bangka Belitung Province, Indonesia. Methods. Process of raw materials beneficiation by washing, vibration on the screen, magnetic separation. Manufacturing whiteware from beneficiated quartz sand, beneficiated kaolin, ball clay and feldspar. The whiteware properties were analyzed in terms of shrinkage, water absorption, flexural strength, and whiteness index. Findings. The amount of iron oxide in the quartz sand and the kaolin was reduced by beneficiation process from 1.12% and 1.06 to 0.51% and 0.5%, respectively. The whiteware specimens showed the required physical and mechanical properties. Thus, these raw materials can principally be utilized for the manufacture of whiteware ceramic items with whiteness index up to 68.3. Originality. Quartz sand and kaolin extracted from tin mine tailings were used after beneficiation of raw materials for whiteware manufacture. Practical implications. This research can provide practical solution to the problem related to mine tailings rich in quartz and kaolin which can be utilized for manufacturing whiteware. Keywords: tin mine tailings, quartz sand, kaolin, magnetic separation, whiteware ceramics
