  It 
  will 
  be 
  observed 
  that 
  the 
  ore 
  in 
  its 
  crude 
  state 
  is 
  not 
  of 
  Besse- 
  

   mer 
  grade. 
  The 
  concentration, 
  however, 
  eliminates 
  sufficient 
  

   phosphorus 
  so 
  that 
  the 
  product 
  can 
  be 
  used 
  for 
  Bessemer 
  pig. 
  

   As 
  a 
  result 
  of 
  the 
  milling 
  operations 
  it 
  was 
  found 
  that 
  the 
  quantity 
  

   of 
  phosphorus 
  passing 
  into 
  the 
  concentrates 
  could 
  be 
  regulated 
  to 
  

   some 
  extent 
  by 
  the 
  crushing. 
  With 
  fine 
  crushing 
  the 
  apatite 
  

   which 
  carries 
  the 
  phosphorus 
  is 
  mostly 
  released 
  and 
  under 
  the 
  

   magnetic 
  treatment 
  goes 
  into 
  the 
  tailings. 
  

  

  Of 
  the 
  shipments 
  made 
  in 
  the 
  first 
  period 
  of 
  operations, 
  a 
  large 
  

   part 
  averaged 
  over 
  60 
  per 
  cent 
  iron 
  with 
  less 
  than 
  .03 
  phosphorus. 
  

   The 
  coarser 
  concentrates 
  carried 
  as 
  high 
  as 
  .47 
  per 
  cent 
  phosphorus. 
  

   In 
  the 
  last 
  campaign 
  in 
  1900 
  and 
  1901, 
  the 
  product 
  of 
  some 
  70,000 
  

   tons 
  averaged 
  from 
  63 
  to 
  64 
  per 
  cent 
  iron, 
  about 
  .037 
  per 
  cent 
  

   phosphorus 
  and 
  .46 
  per 
  cent 
  sulfur. 
  The 
  concentrates 
  were 
  used 
  

   by 
  Pennsylvania 
  furnaces 
  for 
  Bessemer 
  and 
  foundry 
  irons. 
  

  

  The 
  following 
  analysis 
  is 
  of 
  interest 
  as 
  showing 
  the 
  chemical 
  

   constituents 
  of 
  the 
  gangue, 
  which 
  may 
  be 
  considered 
  closely 
  analo- 
  

   gous 
  in 
  all 
  respects 
  to 
  the 
  country 
  rock. 
  It 
  was 
  made 
  from 
  a 
  

   sample 
  of 
  mill 
  tailings 
  produced 
  during 
  the 
  regular 
  course 
  of 
  

   operations.
